Bash History

Interesting list of 15 examples of bash history syntax.

Most people probably know #5:
# !ps
ps aux | grep yp

I didn’t know #13, that looks really useful for arcane purposes:
# cp ~/longname.txt /really/a/very/long/path/long-filename.txt
# ls -l !cp:2
ls -l /really/a/very/long/path/long-filename.txt
