Making Bash Tab Completion Case-Insensitive is Too Convenient

This article introduces how to configure case-insensitive tab completion in the Bash language command line on Linux PCs and servers. You don’t have to worry about uppercase anymore.

yuis on ASUS at /mnt/c/pg/20190318174120$ ls hoge
hoge/     Hogehoge/

Add the following to /etc/inputrc.

set completion-ignore-case On

command line - Can I make Tab auto-completion case-insensitive in Bash? - Ask Ubuntu

Update

Sometimes inputrc doesn’t get loaded even though it worked once. It’s unstable. I’m not sure if it’s because it’s WSL.

bind "set completion-ignore-case on"

Running this as a command makes it work. Instead of writing it in inputrc, it might be more reliable to write this in bashrc.
