How do I ignore file extensions in git regardless of case?

I want to tell git to ignore e.g. jpg files regardless of how the extension is written.

e.g.

*.jpg

should ignore

.jpg, .JPG., .Jpg

etc.

Is that possible without telling git to ignore case altogether?

You can tell git to ignore case in most situations, including in your .gitignore files. All you need is:

git config core.ignorecase true

From a practical point of view, there may be trade-offs involved. The git-config(1) man page says:

   core.ignorecase
       If true, this option enables various workarounds to enable git to
       work better on filesystems that are not case sensitive, like FAT.
       For example, if a directory listing finds "makefile" when git
       expects "Makefile", git will assume it is really the same file, and
       continue to remember it as "Makefile".

       The default is false, except git-clone(1) or git-init(1) will probe
       and set core.ignorecase true if appropriate when the repository is
       created.

So, you may run into trouble if you are on a case-sensitive filesystem. Your mileage may vary.

Git ignore understands glob pattern, so you can use this
