Inputrc deals with the mapping of the keyboard for certain situations. This file is the start-up file used by readline - the input related library used by Bash and most other shells.
For more information see info bash -- Node: Readline Init file as well as info readline. There is a lot that can be done with this one rc file.
The following is a base /etc/inputrc along with comments to explain what the various options do.
Please note that comments can not be on the same line as commands in inputrc.
# Begin /etc/inputrc # Make sure we don't output everything on the 1 line set horizontal-scroll-mode Off # Enable 8bit input set meta-flag On set input-meta On # Turns off 8th bit stripping set convert-meta Off # Keep the 8th bit for display set output-meta On # none, visible or audible set bell-style none # All of the following map the escape sequence of the # value contained inside the 1st argument to the # readline specific functions "\eOd": backward-word "\eOc": forward-word # for linux console "\e[1~": beginning-of-line "\e[4~": end-of-line "\e[5~": beginning-of-history "\e[6~": end-of-history "\e[3~": delete-char "\e[2~": quoted-insert # for xterm "\eOH": beginning-of-line "\eOF": end-of-line # End /etc/inputrc
Global values are set in /etc/inputrc. Personal user values as are set in ~/.inputrc. The ~/.inputrc file will override the global settings file. The previous page sets up Bash to use /etc/inputrc by default. If you want your system to use both, it might be a good idea to place a default .inputrc into the /etc/skel directory for use with new users.
