Sample debug output code for BASH/SHELL

When trying to debug your own scripts it can be difficult to see exactly what you want.  Pages of white text scrolling across the screen.  Here is a quick flexible function that can make life a whole lot easier by setting different debug values and instead of using echo, use the function name.

Copy this into a basic script and run it, adjust the debuglevel variable at the top to see different output.  I know this will help me in the future and hope it will help others as well.

I love Linux, but as we all know we have to work on windows computers usually on a day-to-day basis.  We have servers we constantly have to RDP (remote desktop) into to work with active directory, etc.  The Terminal server client in 10.04 was all buggy and when you closed the window it would reconnect in 30 seconds.  This was especially annoying when you left a session open on your locked computer on the other side of the building and needed to hop on real quick to do something.

I found out that the problem was that certain libraries had bee updated and caused this bug.   I decided using rdesktop for a while would suffice and created a launcher on my panel to run this command.  It wasn’t pretty for the longest time, a bash terminal asking for usernames, etc.  I really didn’t like it.  I stumbled across zenity a while ago and decided to use that to hide the password and pass that to the rdesktop command.  It is pretty simple actually.
I prefer to hard-code my username and domain in so that I don’t have to constantly fill it out, however more zenity windows could easily be added if more security or flexibility would be needed.  I saved this into a script, made it executable, and then created a launcher to run the script.  I haven’t spent much time on it but I could not just put this code into a launcher and run it (on XFCE, I suppose other frontends like gnome2 or unity might work).

The code above in a launcher provides these dialogue boxes:

Username

password

 

Zenity provides a lot of flexibility in bash scripting so end users don’t have to see a techy/confusing bash window to do something simple.  Zenity options:

We will definitely be using zenity to make some things more user friendly…
