Thanks for this. Will try it soon.

Are you saying that you can run the script from the
konsole with "sh myscript.sh" also in addition to
"/bin/bash -c "sudo appname"". Sorry to be so dumb on
the subject but I only attempt to run script out of
absolute necessity.

Never seen the "shebang" line at top of any script
file. guess I need to look harder. What I do see at
the top of most script files is "!/bin/sh". Could you
list at least one script in Kubuntu with that
beginning line.?

Duhh, confused here; please stay with me. Is the root
command "!/bin/bash" the correct one to use and not
!/bin/sh?  At the start of every script file I look
at, is the command? !/bin/sh which I thought
successfully ran the script in the past. Maybe I
misremember. Would you please elaborate on this so I
may fully understand.

I haven't the slightest understanding of this.
Guessing that .sh is a shell script and .pl is a Perl
script and each requires the correct command line
syntax as you mentioned above.

Thanks for trying to help. Obviously I'm a hard fix on
this and have little knowledge on running scripts. I'm
open to any reference on running the script but
definitely not writing or understanding what the
script is doing. Thanks again.
