Octave uses the GNU Readline library for command-line editing and history features. Readline is very flexible and can be modified through a configuration file of commands (See the GNU Readline library for the exact command syntax). The default configuration file is normally ~/.inputrc.
Octave provides two commands for initializing Readline and thereby changing the command line behavior.
Read the readline library initialization file file. If file is omitted, read the default initialization file (normally ~/.inputrc).
See Readline Init File, for details.
Re-read the last readline library initialization file that was read. See Readline Init File, for details.
