The shell scripts are linked in the program by the name and location of the script. What this means is that you can edit any of the scripts and have them do what you want them to do. Shell scripts are plain text files. The scripts are not compiled into the program and can be changed. My adhd is starting to show again.
The little program started out with about 3 or 4 buttons and now we are close to 100 buttons. The scripts that the buttons control do several different things. When including local and remote operations there are close to 250 things that maintain1 can do.
Yes the program is still freeware but donations are welcome.
