lastcomm prints out information about previously executed
commands. If no arguments are specified,
lastcomm will print
info about all of the commands in the
acct file (the
record file). If called with a command name, user name, or tty name,
only records containing those items will be displayed. For example, to
find out which users used command ‘a.out’ and which users were
logged into ‘tty0’, type:
lastcomm a.out tty0
This will print any entry for which ‘a.out’ or ‘tty0’ matches in any of the record’s fields (command, name, or tty). If you want to find only items that match ALL of the arguments on the command line, you must use the ’–strict-match’ option. For example, to list all of the executions of command ‘a.out’ by user ‘root’ on terminal ‘tty0’, type:
lastcomm --strict-match a.out root tty0
The order of the arguments is not important.
For each entry the following information is printed:
This program implements the features of regular u*x
a few extra flags. When
lastcomm is invoked without arguments,
the output looks like this:
nslookup jberman ttypb 0.03 secs Tue Feb 16 19:23 comsat root __ 0.03 secs Tue Feb 16 19:19 uptime ctilburg __ 0.11 secs Tue Feb 16 19:23 sh F ctilburg __ 0.02 secs Tue Feb 16 19:23 sleep ctilburg __ 0.02 secs Tue Feb 16 19:22 ls noel ttyp4 0.19 secs Tue Feb 16 19:23
Print only entries that match all of the arguments on the command line.
List records for user with name. This is useful if you’re trying
to match a username that happens to be the same as a command (e.g.,
