Hi,

How can I find out if an executable is available in the path?

TIA

There is a Python implementation of 'which' that does that here:

'C:\\Python22\\python.EXE'

This works on linux:-

import os

ls=os.environ['PATH']

for d in ls.split(':'):
if 'executable' in os.listdir(d):
print 'found it!'
break
