Read, sort and confirm uniqueness of entries in files and directories

For users looking to simplify management of large entries in files and directories, this command is the key to fun and simplicity. Using the power sort, only a couple of seconds are necessary to accomplish what would take minutes or hours in ?standard? client applications.

Know a better way?

If you can do better, submit your command here.

What others think

less is being misused here. What you really mean is cat filename | sort, or instead:

sort filename | uniq > newfilename

If I am reading the manpage correctly, I think using the -u flag on sort will do the job of uniq: this will also do it:

sort -u filename > newfilename

yeah that use of less didn't look right.

-n sorts numerically

-r reverses

Comment by tobiasboon 319 weeks and 1 day ago

confirming bwoodacre's reading of the man page (I use "sort -u" all the time). His second code snippet does the job.
