Nemo Custom Action (.sh script) does not execute

rated 0 times [ 1] [ 0] / answers: 1 / hits: 5103 / 1 Year ago, fri, december 16, 2022, 3:05:52

I created a .sh script for simple OCR-ing of screenshots that I make with Shutter.
The script looks like this (ocrFile.sh):

#!/bin/bash



convert $1 /tmp/output.pnm

cat /tmp/output.pnm | pamstretch 4 > /tmp/stretched.pnm

convert /tmp/stretched.pnm -colorspace gray /tmp/output600dpi.tif

tesseract /tmp/output600dpi.tif ./outputText -l eng

This script does some image enhancing that is required when OCRing with tesseract.
It does the job properly if it is called from the terminal. What I wanted was to do the whole process within Nemo, so I created a custom action named OCR.nemo_action inside /home/user1/.local/share/nemo/actions with the following content:

[Nemo Action]

Name=OCR The Screenshoot

Comment=OCR Function for Nemo File Manager

Exec=<ocrFile.sh %F>

Icon-Name=gtk-execute

Selection=Any

Extensions=png;

This Nemo action don't produce output with the script given above.
The .sh script is also in the folder for Nemo's custom actions.

Please help!
