I find myself needing this command every once in a while and I can never remember exactly how it goes. It parses through a directory (and subs) to give you a report on how many lines are in each file. It is great for working with csv files.

wc -l `find ./ -name '*.csv'`

I got this from an old post on Dev Shed forums that I participated in. I posted it here so I don’t have to keep seeking out the post every time I am trying to remember this command.

Came across this on digg today. It is another reference sheet for common Linux/Unix commands and programs. It has a lot of good common uses of good programs like scp, rsync, svn, psql and mysql.

This is a great article that compiles over fifty references for both Linux and Unix. It pretty much all command line references, which can be really handy.

Thanks to Scott Klarr for compiling this list of references.
