A simple way to check MD5sum

[ralphy]

Name: Checksum
Description: Calculates  checksum.
Command: /usr/scripts/checksum %f
Pattern: *
Appearance: Check all the boxes except Directories

save the script as checksum
make executable
copy the file to /usr/scripts

I find the script rather useful. I've modified it to allow users to select a file just by launching the script. If the custom action in Thunar is configured, it will allow users to right-click and select files without prompting to browse for the file.

Extract and move the extracted files to their respective locations.

/usr/scripts/checksum
/usr/share/applications/checksum.desktop

Here is what it looks like:











Cheers!
