My service menu doesn't work but the script it calls works in a terminal

[chimak111]

I have this script (courtesy of code from here):

#!/bin/sh
for x
do
for i in 1 2 3 4 5
do
convert -brightness-contrast -${i}0x0 "$x" "${x%.png}-$i.png"
done
done

And this (/home/vasa1/.local/share/kservices5/ServiceMenus/less-bright.desktop):

[Desktop Action less-bright]
Exec=less-bright.sh %U
Name=Reduce Brightness
Icon=colorneg

[Desktop Entry]
Actions=less-bright
MimeType=image/png;image/jpeg;
ServiceTypes=KonqPopupMenu/Plugin
Type=Service
X-KDE-Priority=TopLevel

If I run less-bright.sh from the terminal like this:
less-bright.sh image.png
As expected, I get 5 additional files, image-1.png through image-5.png of decreasing brightness.

However, if I right-click image.png in Dolphin and choose "Reduce Brightness" from the context menu, all I get is just the one additional file, image-1.png. Why is that?

Clutching at straws... The environment that the script gets from dolphin may be different to that from a shell in the terminal. KDE doesn't run .profile or .bashrc and the like when starting these days. In particular, the $PATH might be different, causing a different version of the script to be run.

(If you want stuff set up to affect .desktop files, you can put a script in ~/.config/plasma-workspace/env - note that the script will be run by dash, regardless of a shebang.)

Thanks for looking into this!

Re. the rest, I have two other service menus that use scripts. They work fine. It's not like the script is not working at all when called via the service menu. It just does the first instead of five cycles.

I've put a copy of less-bright.sh in ~/.config/plasma-workspace/env and edited ~/.local/share/kservices5/ServiceMenus/less-bright.desktop accordingly. No improvement. I'll try a log out / log in and see.

EDIT: nothing changed after logging out and logging in. Let's see what happens tomorrow when I restart my system.

I copied and pasted the scripts, and they both worked correctly.
