'locate' for case-insensitive words?

Question

I wonder how to use the command locate to search for words that are not case sensitive? Such as modify locate normal to search for results that have "Normal" and "normal". Thanks!

Answer 1

That depends on the locate you use. There are a couple of implementations, with identical executable names, but various package names: locate, slocate, mlocate, rlocate.

Usually they all have -i and/or --ignore-case switch. Consult your locate's man page for the exact syntax.

Also usually they have no configuration file, so if you want to set the case-insensitiveness persistently, set an alias in your .bashrc (or similar) file: alias locate='locate -i'.
