inputrc file is the configuration
file for Readline library, which provides editing capabilities while
the user is entering a line from the terminal. It works by tranlating
keyboard inputs into specific actions. Readline is used by Bash and
most other shells as well as many other applications.
Most people do not need user-specific functionality so the command
below creates a global
used by everyone who logs in. If you later decide you need to
override the defaults on a per-user basis, you can create a
.inputrc file in the user's home
directory with the modified mappings.
For more information on how to edit the
inputrc file, see info bash under the Readline Init File section. info readline is also a good source
Below is a generic global
with comments to explain what the various options do. Note that
comments cannot be on the same line as commands. Create the file
using the following command:
cat > /etc/inputrc << "EOF"
