You can do what the "which" command does: split the PATH environment variable into individual components, and see if the string maps to a file in any directory in your PATH with the "execute" bit set. That won't catch shell macros, however. You might be able to use "type" to do that. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. -- http://mail.python.org/mailman/listinfo/python-list
