As I wrote yesterday you can define keys for history-search-backward and history-search-forward. A good placement for these commands are the PgUp/PgDown keys since M-p is already defined per default. Put this into your /etc/inputrc or ~/.inputrc : # PgUp/Down searches history in bash \e[5~:history-search-backward \e[6~:history-search-forward If you really want M-p a the key to search bachward, you would have to write this: \ep: history-search-backward For a list of available readline commands look into the bash manpage. To see what a key combination ends up as, type C-v (that's Ctrl V) followed by the key combination. Just translate a leading ^[ of your key combinations into \e in your inputrc.

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.
