for !path, you could read the user's idl.pref file...

The idl executable is a shell script that sets these variables up and then calls the actual binary, so I might be easiest to
take the beginning of this script before it actually calls the IDL binary.

Yeah, but this is not what I am looking for since, in this way, idl
still has to start up.
Any other suggestions?

Well, I don't know if there's any proper non-IDL way, but what you can do:
echo 'PRINT,!DLM_PATH & EXIT' > blah.txt
p=`idl < blah.txt`
echo Here\'s the path: $p
Cheers,
Jo
