Thanks a lot Jason,
I've used the following in programs I write:
def which(program):
def is_exe(fpath):
return os.path.exists(fpath) and os.access(fpath, os.X_OK)
fpath, fname = os.path.split(program)
if fpath:
if is_exe(program):
return program
else:
for path in os.getenv("PATH").split(os.pathsep):
exe_file = os.path.join(path, program)
if is_exe(exe_file):
return exe_file
return None
IIRC, I adapted it from StackOverflow. I know it works on Linux and Mac
OS X, but not sure about windows (since I don't know if PATH works the
same way there).
I'll try it, the script looks reasonably portable (using os.pathsep)
to really replicate which I had probably to add os.getenv('pathext')
as Chris mentioned.
However for my current use case this is not necessarily required.
HTH,
Jason
