how to get weather forecast prognosis from command line text terminal / console on Linux and FreeBSD

Doing everything in Linux console / terminal is a question perhaps every Linux / BSD hacker wants to do as Graphical user interface and using web search or using Graphical Environment plugins is an unneded complexity + googling or duckduckgoing for weather to check your next vacation destination city has been more and more of a terrible experience (for me) as I'm not a big fan of using the OS in a GUI.
In that manner of thoughts, as a Linux console geek and hard core ASCII art fan. I was recently happy to find that  possible to check weather forecast in tty console or Linux terminal in a beautiful ascii art way easily through a Web wttr.in service – a web application weather forecast service that supports displaying the current and few days in future, weather forecast either in browser as a plain text or from the command line by simply accessing it with your favourite web access / transfer tool such as;
wget / curl or any of your favourite text browser elinks / lynx / w3m or if on *BSDs use fetch command.

 

Install Curl data transfer tool if it is not already


Wget is installed by default across most Linux distributions and fetch is present by default on BSDs, displaying it in text browser would perhaps be never used but if you decide to give it a try maybe try with elinks (to get colorful output), w3m and lynx will display a black and white results.

In case if you miss curl, install it:

On Debian distro

 

aptitude install -y curl


or Fedora

yum install -y curl


Of course to use wttr.in as it is Internet based Weather Forecast service the minimum you need to have is to have Internet connection to your Linux / BSD desktop computer.

Text based Weather Forecast Web App currently supports:

display the current weather as well as a 3-day weather forecast, split into morning, noon, evening and night

  • Temperature is displayed for morning, noon, evening and night (includes temperature range, wind speed and direction, viewing distance, precipitation amount and probability)
  • Provide results for Weather based on City / town / village location
  • Supports display of Moon Phases Forecast in calendar days
  • Supports multilingual names (Bulgarian Phonetic cyrillic / Russian and other exotic UTF-8 encodings such as Chineese and Japanese),  50+ languages are currently supported
  • Has ability for prognosis for hostname (domain) location based on an its IP GeoIP location on the Globe
  • Geographical locations / landmarks such as Lakes / Mountains etc. can be easily queried
  • Query results metrics could be configured, e.g. USCS units or EU and rest of world accepted ones (SI) metric
  • Displayed result could be either in ANSI (if from terminal / console / HTML if queried from browser or in PNG – if needed)

 

Where wttr.in could be useful ?

The best applications use, I can think of are for server (shell) / perl scripting automation purposes, it could be useful especially in TOO HOT, TOO, COLD, TOO WET location in Small and Middle sized Data Centers Green Energy (Sun Panel) Parks / Wind Energy situated Linux monitoring hosts to track possible problems of overheats or overcolding of servers due to abnormal excessive temperatures such as the ones we experienced this summer here All across in Europe or in too Cold DC locations such as heat locations Deserts in African Countries, Saudi Arabia or Chukotka or Siberia in Russia.
Other application is as a backup option to other normal Weather report services by PHP or Python scripts that fetch data, from multiple places.
Of course since this is a third party controlled service, the downtime is due to excessive connection requests, the service could get flooded and stopped working, but I guess for any Commercial use, wttr.in creator Igor Chubin would be happy to sell a specific crafted service for any end user candidates.


Here is few examples of the beautiful returned ASCII art formatted output of wttr.in.
 

1. Getting a three days Weather Forecast prognosis for city / town location

To get what is current weather in my current city of Living, Sofia Bulgaria just pass the city to the URL address

curl http://wttr.in/Sofia

text-console-wttr.in-Weather-forecast-Sofia-for-Linux

 

links http://wttr.in/Dobrich

 

curl-Linux-show--Dobrich-Weather-forecast-in-lynx-text-browser


Default links (Linux) www text browser produces ugly black and white

2. Displaying Weather forecast with wget

 

wget -O- -q http://wttr.in


getting-weather-forecast-on-linux-terminal-console-with-wget-command

If you're lazy you can even omit the http:// as wget will look for HyperText Transmission Protocol by itself

 

wget -O- -q wttr.in

 

3. Getting Forecast results for a Tourist Destination


Lets get the weather forecast for the popular tourist Bulgarian destination of the Seven Rila Lakes (near Rila Monastery), situated in the Rila Mountain BG.

 

curl http://wttr.in/Seven+Rila+Lakes

 

Console-terminal-Weather-forecast-Linux-Seven-Rila-Lakes

 

 

4. Display Forecast for a specific server IP


Displaying information on specific server IP address current situated in GeoIP database, of course could be not really true, as the IP could be just a Load Balancer a router that does NAT to some internal DMZ-ed location server, but anyways it is a cool feature.

Lets get information on what is the weather on Google Global's Public DNS server IP 8.8.8.8 so commonly used to guarantee a Windows and Linux Desktop client machines Internet connectivity.
 

curl wttr.in/@8.8.8.8

 

wttr.in-Linux-text--forecast-service-curl-screenshot Google Public DNS location weather forecast

5. Download PNG image picture from wttr.in service

 


Lets say you want to get a 3 days standard Weather forecast for the popular Black Sea Resort town in Bulgaria Pomorie (a beautiful sea city which has even a functioning 5 Monks Monastery Pomorie Monastery situated near sea coast)

 

curl http://wttr.in/Pomorie.png

8. Comparing two cities weather from command line

 


One useful use of wttr.in if you plan to travel from Location city A to Location city B is to compare the temperatures with a simple bash one liner script:

 

 

 

diff -Naur <(curl -s http://wttr.in/Sofia ) <(curl -s http://wttr.in/Beograd )

 

 

9. Using ansiweather command to get Weather Temperature / Wind / Humidity in one line beuatiful text

 


If you go and install answeather Linux package

 

apt-get install –yes ansiweather


You will get a shell script wrapper with ANSI colors and Unicode symbols support. Weather data comes from OpenWeatherMap, this is useful if wttr.in is not working due to some URL malfunction (due to service is DoS-ed) etc.

 

ansiweather -l Atina

 

ansiweather-Atina-weather-forecast-result-linux-text-console

Lets use ansiweather to print the weather prognosis for upcoming 5 days for near port of Burgas, BG
 

ansiweather -F -l Burgas

ansiweather-print-weather-forecast-prognosis-for-5-days-in-Linux-text-terminal

 

10. Get all Weather current forecast for each Capital in the world


You can download and use this simple plain text file list of All Country Capitals in the World (country-capitals-all-world.txt) with ansiweather and a bash loop to get displayed each and every current day Weather Forecast in the World, here is how:

 

while read line; do ansiweather -l $line; sleep 3; done < country-capitals-all-world.txt


ansiweather-all-countires-capitals-result

As you can see some of the very exotic third world capitals does not return data so 'ERROR: Cannot fetch weather data' is returned.


You can also substitute ansiweather with curl wttr.in/$line to do get the beautiful ASCII art 3 days weather forecast via wttr.in

 

while read line; do curl http://wttr.in/$line; sleep 3; done < country-capitals-all-world.txt


I'll be happy to know other nice ASCII Art supporting Web service to enjoy from text terminal on Linux (nomatter useful or) just funny joyful prank maniacal pranks such as Watching text ASCII version remake of Star Wars Classic Movie by simply telnetting to towel.blinkenlights.nl (if you haven't so just telnet and enjoy the streamed ASCIIs ! 🙂

Talking about fun and ASCII, its worthy to mention hollywood Linux package

hipo@jeremiah:~/Desktop$ apt-cache show hollywood|grep -i desc -A 3
Description-en: fill your console with Hollywood melodrama technobabble
 This utility will split your console into a multiple panes of genuine
 technobabble, perfectly suitable for any Hollywood geek melodrama.

To give you an idea what to expect, here is shot of /usr/games/hollywood (the program start binary location) on Debian GNU / Linux running, Enjoy! 🙂
 

Intel and IBM future tech world vision about the world, do we really want this?

Saturday, June 30th, 2012

Reading Time: 2 minutes

the-hellish-future-as-envisioned-by-leading-it-companies-IBM-and-intel-and-the-slavery-of-Internet-of-Things

I'm quite a visionary person as such I'm always interested to prognosis on what the world might look like few years from now. Below are two videos showing IBM and Intel's vision on what might future bring us. I don't know about you but I'm strong in my conviction that I DON'T WANT TO LIVE IN SUCH WORLD. I'm pretty sure that many other people share my opinion that such a world is not fun and is far from what really we're supposed to live. The sad thing is the corporations are already powerful enough to impose their vision and make the vision reality.

It is my understanding that the main problem we have to solve is not how we can embed better or newer technology to change our life (for good?) but rather how we can get out of the trap of living in a fake world like the one displayed in the video. Obviously the vision of this two giant companies is not far from what we're forewarned in the holy bible in Revelation. In revelation we read that there will be a unified system, where everything and everyone on this earth will be market and whoever does not have the mark "of the beast" he will not be able to buy or sell within the system. This prophecy closely matches the vision of future marketing offered as a possible outcome by IBM. I don't think IBM have red in Revelation to get their idea on their infernal system shown within their vision of supermarket video

The logical conclusion might dirive therefore is there is a higher force who leads IBM (and possible most if not all of corporations) on creating the fake tech-nocrat culture society which is building right in front our eyes.
The destruction of real communities and the worsening conditions within the Orthodox Church are another symptom that the End Times as prophecised centuries before are closer than we think.

It is my firm believe that people who does understand about this problem should start uniting and say no to technology innovation that leads us in this technological trap ,,,,,

I'm sure even people who does not have a believe in Jesus Christ and are not Christian from other religions are also seeing that the direction this world has taken up is dark.
We should be very dumb and blind not to see that technology is boxing us and leading us to a modern day techno slavery …..

How and Why Walt Disney Is Trying To Corrupt You and Your Children

Thursday, May 24th, 2012

Reading Time: 2 minutes

I've seen a number of videos exposing, a lot of symbolism, occultism and evil contained in Walt Disney's most famous videos.

I've been amazed that a first glimpse innocent looking cartoon can contain so much magical stuff, occult and hidden satanic symbolism.
Its been amazing that we still, are continuously flooding the youth with such openly anti-christian contained cartoons.

I guess even a lot of Christian devoted couples are playing this evil message movies.
On the first look it is not immediately evident what is happening in the movies, a kid could never understand how much bad stuff is contained inside. However a grown parents can easily see if they observe the movies closely. If you don't believe me check the few videos below and also just play some of your favourite kids cartoon and do a critical analysis of what is inside. There is no doubt there is everything inside, everything instead of our Saviour Jesus Christ.
We have become terribly crazy, since we learn the kids to look for anti-Christian lives, even from the very early stages of their childhood.

The result from such movies in the growing up youth is clear; they are attracted to movies with murder violence, sex related plots, stealing lies, ungodly music, love for evil and not a search for good, hatred, betrayal and all the evils, our grandfathers were teaching us to avoid …

How and Why Walt Disney Is Trying To Corrupt You and Your Children

Was Disney Satanic – Part 1

Was Disney Satanic – Part 2

Disney is pure evil

Journalism – How Disney Movies Corrupt Young Minds

There are plenty of psychological books explaining the badness over a child mind of such movies, yet parents are not careful to protect their children but rather encourage them to watch disney's production thinking they help the kid to develop their brain …
If you're a Christian and you know this things exist and they're preached, please be careful and try to select carefully what kind of movies you play to your kids.

If you're a grow up Christian and you've been raised with this movies, don't be in wonder why you have a very severe desire for sex, money, power and occult. The desire for all this ungodly things was 'installed' in you since the time of your youth simply by being bombarded with Disney's, Hanna Barbera and the rest of the 'all times cartoon' American popular cinema and cartoons.

Drawing GANTT Charts and Project Management on Linux, (Microsoft Project substitute for Unix)

Tuesday, October 12th, 2010

Reading Time: 3 minutes

I'm studying Project Management, right now. In that spirit of thoughts I and a couple of other guys are building a Project Plan.
As it Project Plan it's necessary to put a GANTT Chart in it to show visually the project timeline (the phases), the duration and the inter-relation between the different tasks which leads the project to an actual completion.

After a bit of thorough research online on available software to deal with project management and particularly, ones that are capable to build a GANTT charts on Linux / BSD.

I've come with the following list of software capable to be a substitute for the Microsoft Project software.
Redmine GANTT Chart

GANTT chart Redmine

1. Gantt Project
GANTTProject chart GANTTProject Chart

2. Gnome Planner
Planner GANTT Gnome Chart Planner GANTT Chone Chart

3. Task Juggler Project Manager with GANTT Capability for (KDE)
Task Juggler

4. JxProject – This software is not free, though it can be considered almost free
Take a look also at:
5. Trac , though it doesn't really support GANTT charts it's a lovely software to be used for PM.
Trac Project Management

Another option you have is to try out:
6. PHProjekt

Update 20.09.2016 – PHPProject Old download link is no longer active

It is this link http://www.phprojekt.com/, but the page doesn’t seem to be active any more. I thought you might want to update.

If you are looking for an alternative please check out http://wiht.link/PHProjekt-PM, it may make a suitable replacement.

Kind Regards,
Tom Wilcox


That piece of softwre really looks promising, especially if we consider that it's web based and how much essential is today to have an anline tools for doing the ordinary desktop jobs.

You can even check an online demo of the PHPProjekt software here

If you're a type of KDE user you definitely has to try out Kplato

As I've tested the software the software is easy to be used, however it still is missing some essential parts that Microsoft Project includes so it's not 100% substitute.
Also it's not able to open Microsoft Project (MPP) files, neither able to save the charts in the .mpp format.

Moving ahead I've came across DotProject DotProject Gantt Chart
DottProject Gantt Chart

I haven't took the time to test it myself but however, as I go through the software website the project looked quite good.
Lastly you can take a look at: 7. PStricks as a mean of project management, however I think it doesn't support GANTT chart building.

Must have software on freshly installed windows – Essential Software after fresh Windows install

Install-update-multiple-programs-applications-at-once-using-ninite

If you're into IT industry even if you don't like installing frequently Windows or you're completely Linux / BSD user, you will certainly have a lot of friends which will want help from you to re-install or fix their Windows 7 / 8 / 10 OS. At least this is the case with me every year, I'm kinda of obliged to install fresh windowses on new bought friends or relatives notebooks / desktop PCs.

Of course according to for whom the new Windows OS installed the preferrences of necessery software varies, however more or less there is sort of standard list of Windows Software which is used daily by most of Avarage Computer user, such as:
 

I tend to install on New Windows installs and thus I have more or less systematized the process.

I try to usually stick to free software where possible for each of the above categories as a Free Software enthusiast and luckily nowadays there is a lot of non-priprietary or at least free as in beer software available out there.

For Windows sysadmins or College and other public institutions networks including multiple of Windows Computers which are not inside a domain and also for people in computer repair shops where daily dozens of windows pre-installs or a set of software Automatic updates are  necessery make sure to take a look at Ninite

ninite-automate-windows-program-deploy-and-update-on-new-windows-os-openoffice-screenshot

As official website introduces Ninite:

Ninite – Install and Update All Your Programs at Once

Of course as Ninite is used by organizations as NASA, Harvard Medical School etc. it is likely the tool might reports your installed list of Windows software and various other Win PC statistical data to Ninite developers and most likely NSA, but this probably doesn't much matter as this is probably by the moment you choose to have installed a Windows OS on your PC.

ninite-choises-to-build-an-install-package-with-useful-essential-windows-software-screenshot
 

For Windows System Administrators managing small and middle sized network PCs that are not inside a Domain Controller, Ninite could definitely save hours and at cases even days of boring install and maintainance work. HP Enterprise or HP Inc. Employees or ex-employees would definitely love Ninite, because what Ninite does is pretty much like the well known HP Internal Tool PC COE.

Ninite could also prepare an installer containing multiple applications based on the choice on Ninite's website, so that's also a great thing especially if you need to deploy a different type of Users PCs (Scientific / Gamers / Working etc.)

Perhaps there are also other useful things to install on a new fresh Windows installations, if you're using something I'm missing let me know in comments.

Use mac PC built-in camera to make / take pictures on Mac OS X macbookair notebook with Photo Booth

Friday, February 26th, 2016

Reading Time: 3 minutes

take-picture-or-video-with-built-in-camera-on-MacOSX-PhotoboothLOGO

It seems we lost our Good high quality Digital Camera somewhere and I was in need urgently to make a good quality photo (my ZTE Phone) has a very bad camera, so I got the idea to use Macbookair's camera as it has better
resolution to picture my present a  Tank Tort 🙂 hand made by my wife as a present for the Day of the Defender of the Fatherland which is a major feast in Russia, Belarus and many of the ex-Soviet Union members communist countries.

Actually using build in camare in MacBookAir is a handy thing for people mising at the moment a good high quality digital camera as it is thin and light and build in MacBook cam can be used to make Videos and Pictures exactly the same way
as an ordinary Tablet Computer is used so commonly nowadays by many:

In other words I needed for the Mac OS X equivalent to Cheese's (Photo and Video) capturer program for Linux.

Luckily for people interested in using their Mac OS notebook as a amateur camera this is easy by using default shipped Mac Application called:

Photo Booth app

To Launch Photo Booth app it just look it up in Finder and double click it:

PhotoBooth-how-to-take-photos-on-macosx

Clicking the large red button underneath the preview area will take a picture after an optional countdown.

Tort Tank of Svetka

Besides being able to capture Video and Pictures from Mac's camera it could add also some nice effects to taken pictures and videos (supports a basic video editing) features and effects.

The effects you can choose are are: Sepia, Black and White, Glow, Comic Book, Normal, Colored Pencil, Thermal Camera, X-Ray, and Pop Art. There are also effects that change the person in the picture using these effects: Bulge, Dent, Twirl, Squeeze, Mirror, Light Tunnel, Fish Eye, and Stretch. Actually  photographic filters of Photo Booth are very similar to Adobe Photoshop.

make-picture-on-mac-photobooth-effects-screenshot
By default Photo Booth will create picture, howver

Photo Booth saves your photos as JPEG files in a folder named Photo Booth, located in your home folder.

Choose File > Reveal in Finder

to see your picture files.

A much better way to be able to easily see and access all taken Pictures and Videos with Photo Booth is to

 

open Terminal

 

and type:

——-
 

 

$ cd Pictures
$ ln -s Photo\ Booth\ Library/Pictures/ PhotoBoothPics


This will make Link to pictures be easily accessible from your Finder -> Pictures folder
 
Applying custom photo backgrounds

A very useful feature of Photo Booth is that the user can apply backdrops to provide an effect similar to a green screen. When a backdrop is selected, a message appears telling the user to step away from the camera. Once the background is analyzed, the user steps back in front of the camera and is shown in front of the chosen backdrop.

For people who prefer to take photos using a console program on Mac OS I guess you should take a look at ffpeg
Here is one more snapshot of the Tort Tank snapshot made with the Macbookair of Svetlana 🙂

P.S. If you like the Tort Tank and you happen to live in Sofia Bulgaria, you can order it  by dropping me a comment with request 🙂

Enjoy ! 🙂

How to find and Delete Duplicate files in directory on Linux server with find and fdupes command

Monday, March 16th, 2015

Reading Time: 3 minutes

search-duplcate-files-linux-command-and-graphical-tools-how-to-find-duplicate-files-on-linux-mac-and-windows-os

Linux / UNIX find command is very helpful to do a lot of tasks to us admins such as Deleting empty directories to free up occupied inodes or finding and printing only empty files within a root file system within all sub-directories
There is too much of uses of find, however one that is probably rarely used known by sysadmins find command use is how to search for duplicate files on a Linux server:
 

find -not -empty -type f -printf “%s\n” | sort -rn | uniq -d | xargs -I{} -n1 find -type f -size {}c -print0 | xargs -0 md5sum | sort | uniq -w32 –all-repeated=separate

If you're curious how does duplicate files finding works, they are found by comparing file sizes and MD5 signatures, followed by a byte-by-byte comparison.

Most common application of below command is when you want to search and get rid of some old obsolete files which you forgot to delete such as old /etc/ configurations, old SQL backups and PHP / Java / Python programming code files etc.

If you have to do a regular duplicate file find on multiple servers Linux servers perhaps you should install and use  fdupes command.
On Debian Linux to install it:

root@pcfreak:/# apt-cache show fdupes|grep -i descr -A 4
Description: identifies duplicate files within given directories
 FDupes uses md5sums and then a byte by byte comparison to find
 duplicate files within a set of directories. It has several useful
 options including recursion.
Homepage: http://code.google.com/p/fdupes/

 

root@pc-freak.net:/# apt-get install –yes fdupes

To search for duplicate files with fdupes in lets /etc/ just run fdupes without arguments:

 

root@pcfreak:/# fdupes /etc/
/etc/magic
/etc/magic.mime

/etc/odbc.ini
/etc/.pwd.lock
/etc/environment
/etc/odbcinst.ini

/etc/shadow-
/etc/shadow


If you want to look up for all duplicate files within root directory:
 

root@pcfreak:/# fdupes -r /etc/
Building file list /

 

You can also find duplicate files for multiple directories by just passing all directories as arguments to fdupes

 

root@pcfreak:/# fdupes -r /etc/ /usr/ /root /disk /nfs_mount /nas


The -r argument (makes a recursive subdirectory search for duplicates), if you want to also see what is the size of duplicate files found add -S option

 

fdupes -r -S /etc/ /usr/ /root /disk /nfs_mount /nas

 


If you want to delete all duplicate files within lets say /etc/

 

root@pcfreak:/# fdupes -d /etc/

fdupes is also available and installable also on RPM based Linux distros Fedora / RHEL / CentOS etc., install on CentOS with:
 

[root@centos~ ]# yum -y install fdupes


There is also a port available for those who want to run it on FreeBSD on BSD install it from ports:

 

freebsd# cd /usr/ports/sysutils/fdupes
freebsd# make install clean


If you have a GUI environment installed on the server and you don't want to bother with command line to search for all duplicate files under main filesystem and other lint (junk) files take a look at FSlint

Do you wonder How to change <meta name="Generator" content="Joomla! – Copyright (C) 2005 – 2007 Open Source Matters. All rights reserved." /> in Joomla 1.5

If yes, Here is how I've just found to remove the:

 

in my Joomla installation.

I need to remove that as a part of making my website not to leak out that it runs on top of Joomla.

So here is how:

1. Go to your Joomla website main root directory
2. Edit /libraries/joomla/document/html/renderer/head.php
Look for line: 83 in the /libraries/joomla/document/html/renderer/head.php
There you will notice the code:

$strHtml .= $tab.'<meta name="generator" content="'.$document->getGenerator().'" />'.$lnEnd;

In order to remove the <meta name="generator" content="Joomla …." /> change the above code to something like:

$strHtml .= $tab.'<meta name="generator" content="My Custom Web site Generator name" />'.$lnEnd;

That's all now next time you refresh your website the content="Joomla! – Copyright (C) 2005 – 2009 Open Source Matters. All rights reserved." will be no more.
Cheers! 🙂
