Using csh & tcsh

Command Editing in tcsh

tcsh lets you interactively browse up and down through your history list, selecting and editing commands before executing them.

Use CTRL-P and CTRL-N (or up arrow and down arrow) to move up and down through your history list. Each recalled command is displayed on the current command line. To execute the command, hit RETURN. To cancel it, hit CTRL-C.

To edit commands, tcsh provides a command line editor that uses emacs-like or vi-like key bindings. Select the appropriate set using bindkey -e or bindkey -v. Some of the most useful editing commands are shown in the rest of this section. (Use bindkey with no arguments to see all your key bindings.)

emacs Mode Editing Commands

In emacs mode, characters are inserted into the command line unless they are editing commands. You can move the cursor or delete characters using the commands shown below.

Table B-1. Cursor motion commands
