Favorite command line trick in Bash


A question to all unstableme followers, readers and visitors

Whats your favorite command line trick in Bash ?

My favorite one is Bash process substitution:


diff <(sort file1) <(sort file2)


Please comment your favorite one. Bash useful command, command line trick, One liner, vi editor tip or anything related to bash. Please.

Difficult to pick one. Probably one of the ones I use most is pipes.

Yep, the favorite one is difficult. But I can tell one I use most often besides _ls_ and such. It is _help test_ ;-)

I like to use diff with the options -y --left-column to locate the changes between the two files more rapidly.

find . -iname "foo*" is great too -- the iname is case INsensitive.

du -h --max-depth=1 helps me keep an eye on my drives' available space.

I'm still learning, so I look forward to picking up some new ones here!

Anne.
