bashreadline

In bash readline, how do I make the incremental search case insensitive

At the bash prompt, I can type Ctrl-r and Ctrl-s to perform incremental search of my command history.

However, the search is case sensitive: If I have a command cat SomeFile.txt, and I hit "Ctrl-r somefile", I get nothing.

Is there a way to make that search case-insensitive?

  • Short Answer: No you can't get this feature in BASH at present because this feature hasn't been built yet into vi or emacs mode. As I commented above completion-ignore-case only applies to completion, not to isearch.
