Ok, I changed scripts again [not posted yet]; shell scripts are now path [to which they are copied to] independent.
By the way I changed xml files because a
to was missing in »Do you want install ipdfx?«. Yes, English isn't my mother tongue.
@ scotty. thanks for inspiration of
export scriptdir=`/usr/bin/dirname $0`. Usage of export should be optional for my scripts, because they don't start a 2nd script or a binary. Right?
