I have the following code
rm "$torrent"/*.{txt,nfo,jpg} && echo "removed \"txt,nfo,jpg\" files"
If there are no files to delete then I get the "missing operand" error which I would like to avoid because it triggers an exit 1 for the script.
If I have the following code
rm -f "$torrent"/*.{txt,nfo,jpg} && echo "removed \"txt,nfo,jpg\" files"
the rm always evaluates to true even if there were no files deleted.
I want to display the message "removed .. files" if some files were deleted. If no files were deleted I want silence with no errors thrown.
I toyed with
find "$torrent" -type f -name "*.txt" -or -name "*.nfo" -or -name ".jpg" -delete && echo "files were deleted"
but it always evaluated to true even if no files were deleted.
Just rewrite it into a proper if statement:
if rm "$torrent"/*.{txt,nfo,jpg}
then
echo "removed \"txt,nfo,jpg\" files"
if
This allows you to react to the exit status while set -e is in effect, without the script exiting
