checksums

[misko_2083]

This is a script I made for the thunar custom action.
Depends on zenity and pv.
Calculates md5, sha1 and sha2 sums.
I use pv to show progress with zenity --progress dialogue.
Make sure to install pv

apt-get install zenity pv

-save the script as checksum
-make executable
-copy the file to /usr/local/bin

This is how to setup a Thunar Custom Action:
Name: Checksum
Description: Computes checksum.
Command: /usr/local/bin/checksum %f
Pattern: *
Appearance: Check all the boxes except Directories

After setting this up, you can  right click on an *.iso file and test this.

If you don't want to install thunar file manager, you can use a version with file-selection dialogue:
