Test if a linux command is available with Spawn [message #86171]

Hi IDLers,

I want to write a clipboard copy/paste function with IDL on Linux
systems. This is really straightforward with xclip. I just need to know
if the system I am working on has xclip installed. Based on
cgHasImageMagick, I could do:

IDL> Spawn, 'xclip -version', result, error_result

But xclip returns the version in the STDERR stream:

IDL> print, result

IDL> print, error_result
xclip version 0.12 Copyright (C) 2001-2008 Kim Saunders et al.
Distributed under the terms of the GNU GPL

This ok for me, but how to be sure that this is the case on all linux
systems?

Is there a "more general way" to do this?

Thanks a lot,

Fabien
