This solution makes a few assumptions... but it should work in the majority of cases. The principle is that Python is, in my experience, *usually* installed as python2.4 or whatever - even ./configure && make && make install in the tarball makes python a symbolic link to a python2.4 executable. Assuming that this is the case, and that python2.4 will never be any other version of Python: #!/bin/sh APPPATH=/path/to/app PYTHON=`which python2.4` if [ $? != 0 ]; then echo "This program requires Python 2.4 to be installed." >/dev/stderr exit 1 fi "$PYTHON" "$APPATH" "$@" Problems: Requires Python 2.4 to be installed as python2.4, and doesn't have upward compatibility (i.e. 2.5). But it's at least as good as #!/usr/bin/env python2.4, and it gives a clean error message. -Michael -- http://mail.python.org/mailman/listinfo/python-list
