Today I was trying to do a XDMCP connection to the other server ( which is solaris, not sure if that matters) so I used the Xnest server. and used the following command:

Continue readingI wrote a blog on bash script to change the icon/cursor theme using a bash script. Lets extend the same concept a little more and use the script to change the gtk theme for gnome and at the same time take a screenshot also.

set -o nounset # Treat unset variables as an error
With this all the unbound variables as errors and was problem with all the shell scripts that was being sourced in the startup of bash. So all I had to do was remove this from all the startup scripts and then from the skeleton of the bash script in vim :).
