Here is a method I frequently use to replace the which
command. (air code)
import os
pathlist = os.environ["PATH"].split(":")
def which(target)
for p in pathlist:
fullpath = p + "/" + target
if os.path.isfile(fullpath):
return fullpath, True
return "", False
Cleaner is to return the path if found, or None if not.
target, found = which("pandoc")
if found:
target will contain the full path to pandoc
else:
pandoc was not found
You want to check for execute permssion too.
