Today, I wanted a quick utility to help me enter passwords for encfs during
mount.
I was looking for something plain, simple and userfriendly.
At the end I ended up to use the shell for it.
Yes, using dialog/Xdialog you can be a GUI programmer in minutes.
If the text is scrambled, you can download the script here.
Cheers!
