Want to make a bash script that removes a png file if a jpg has the same name.


And I don't know quite what to do

I want to find all .png images in a directory, and remove them if there exists in the same directory a .jpg which has the same filename (not including extension).

It seemed that this was the right place to learn the tricks I need. Any tips?

Code:
for file in *.jpg; do
    [[ -f "${file%.jpg}.png" ]] && rm "${file%.jpg}.png"
done
This is something you may be able to do interactively in the shell when your BASH skills improve a bit.

The expression "${file%.jpg}.png" changes the extension to .png using name expansion.

Yay thanks! My skills do need to improve, but the learning is the fun part anyways, so I don't mind that at all.
