[NCLUG] Shells and stuff...

[Jim Wildman]

That's an interesting sequence.

Don't forget about the 'fc' command too.

Essentially, bash has done a Borg job on almost every good command line
feature of the other shells and can behave like one of them with a
little persuasion.  I routinely use csh history commands (!!, !?, !-4,
!:s/pat/newpat/) in bash.  Can always tell when someone has come over
from the windows world...they think the up arrow is the key to all shell
history.
