You are refering to the use of "/bin/sh -c 'command'" in order to run
arbitrary shell commands in the "Exec" handling?  This will run
/bin/sh.  However...

On your system /bin/sh may or may not be bash.  On many systems it is
linked to dash.  If it is dash or other then it won't run any bash
specific environment script.

I think so too.  However I will suggest an alternate plan.

I suggest using X resources with different names.

For example with XTerm you can create these X resources entries.  (You
may not be using an XTerm but since you didn't say I will assume
something generic and hope it applies to your specific program.)


For the example above if I invoke an xterm normally like this then I
get green on black with the default 80x24 size.

  $ xterm &

On the other hand if I assign the name "debug" then it will use the
"debug" X resources.  It will be white on black and 80x50.

  $ xterm -name debug &

And if "editor" then it will use the editor resources.  It will be
yellow on black and 132x80.

  $ xterm -name editor &

Simply assign the different configurations you wish to the different

Eww...  Putting that into /etc/profile polutes everyone's
environment.  Not good.
