If you're using bash, and the command you want to retrieve was typed
in the last 500 or so commands, try "ctrl-r ls" which should recall
the most recent command with the string "ls" in it.

You can also use the "history" command to view your history.  Any
command in your history can be reused by prefixing its history number
with a bang ('!').  Thus if history says "422  ls -lAF /usr/local" you
can type "!422" at a prompt to issue that command again.  history +
grep can be fun.

Finally, (and perhaps most obvious) you can use ctrl-p and ctrl-n to
cycle backwards and forwards through your command history.  For most
terminal types these sequences are mapped to the up-arrow and
down-arrow respectively.
