md5 checker with progress bar

Misko_2083 · 2016-04-03 12:22:19

Sharing the bash script I made last night.
This script calculates md5 for single and multiple files selected. For single files it has the option to compare the calculated checksum with the one usually provided in md5 files.
Dependancies are pv, zenity and xsel (optional or in other words just for fun big_smile ). If xsel isn't installed the script will open a text box so you can manualy enter/paste md5 and also display a small tip to install xsel. xsel is used to auto-use the checksum in the clipboard.

Setup:
Save the script to /usr/local/bin/md5checksum.sh, make executable chmod +x
Set the thunar custom action
Command:

temp=$(mktemp /tmp/XXXXXX); > $temp; for file in %N; do echo $file >> $temp; done; /usr/local/bin/md5checksum.sh $temp; rm -f $temp

Appearance conditions:
Pattern: *
Appers for: Audio, Video, Text, Image and Other Files
