You can leave the device commands in the file and skip the bash,
doing it all in IDL. Here is the system I use.

1) I have my IDL_STARTUP env. var. pointing to idl.pro
2) I made a file link: % ln -s idl.pro idl_noX.pro
3) I have a bash alias: alias idl_noX='export IDL_STARTUP="idl_noX.pro"'
4) When I need to run without X, I type "idl_noX" at the CLI

Finally idl.pro (which is *also* idl_noX.pro) contains this:

env = GETENV( "IDL_STARTUP" )
IF ( STREGEX( env, 'noX', /BOOLEAN ) ) THEN x = 0 ELSE x = 1
IF x THEN device, true = 24
IF x THEN device, decomposed = 0
IF x THEN device, retain = 2
delvar, env, x

-k.
