How do I reload .inputrc?

By default, C-x C-r is bound to re-read-init-file.

See the Bash Reference Manual for explanation.

You can also reload new entries from command line using bind -f ~/.inputrc. That will load the entries in .inputrc. Note that it just does a load, not a "reload" - so it doesn't reset any lines you happen to have removed from the .inputrc.

To quickly test from a clean slate, just run bash then work inside that new nested shell (or start a new terminal).

This worked for me

bind -f ~/.inputrc
