[lug] bash scripting question

[Jeffrey Haemer]

Chip,

For bash, going straight to the man page is productive.  You can search it
for whatever symbols you want. And you'll need to -- it's big. Here are
linecounts of the ten biggest man pages of utilities in /bin on my box:


566 ed
637 grep
732 dbus-daemon
1131 ps
1559 ip
1563 less
1589 dash
2029 mount
4989 busybox
5375 bash


Modulo size, it's also quite good.
