I want history-search just like in tcsh. How can I bind it to the up and down keys?
Just add the following to /etc/inputrc or your ~/.inputrc
Then restart bash (either by logging out and back in, or by running exec bash).
Readline (the part of bash that handles terminal input) doesn't understand key names such as "up arrow". Instead, you must manually discern the escape sequence that the key sends on your particular terminal (usually by pressing Ctrl-V and then the key in question), and insert it into the .inputrc as shown above. \e denotes the Escape character in readline. The Ctrl-V trick shows Escape as ^[. You must recognize that the leading ^[ is an Escape character, and make the substitution yourself.
