Grepping my history of commands has been very helpful to me with my Linux
learning process, so I want to take the help one stage further to keep track
of all command history.
Before I embark on a mission to teach myself enough Perl to do the job. Is
there already a utility which will let me.
capture the output of my history to a sorted text file which contains no
duplicate lines.
I can get the sorted file easy enough with
history | sort > sortedhistory.txt
and regularly updated it with
history | sort >> sortedhistory.txt
So the main problem is getting the duplicates out of the sortedhistory.txt
file. What do you reckon, a good job for a Perl program ?
