The Next Ten One-Liners from CommandLineFu Explained

My favorite is the modifier for histories.

$ ls a b c

a b c

$ ls !$

ls c

c

$ ls a b c

a b c

$ ls !:3 !:2 !:1 !:0

ls c b a ls

ls: ls: No such file or directory

a b c

$

Ah, what a cool page that CommandLineFu is... :)

I didn't know that pipes can work with remote commands before, what amazing combinations!

They don't -- they work with the local ssh command. Its just that ssh when invoked with a "command argument" runs that command instead of a shell, with the stdin and stdout being run through the network.

The end result is similar to what you said, but the mechanism is different, the pipe itself is strictly a local construct.

Thanks for pointing out that :)
