Is there a function in python that does what "locate" does in a bash
shell?
I know I could do it by using os.popen('locat e'), but I'm curious if
there's a Python "native" way to go about it. Only needs to work in
Unix, but would be interesting if it was cross-platform.
Thanks.
Here is a quick hack I just did, its very ugly, but does the job.
First do locate -u to create a cache then just locate [term], its not so
fancy as to remind you when the cache is too old, but hey.
It requires Python 2.3+
Hope this helps.

cache.close()

def cache():
cache = file("files.cac he", 'w')
for root, dirs, files in os.walk(rootPat h):
for aDir in dirs:
cache.write("%s \n" % aDir)
for aFile in files:
filePath = os.path.join(ro ot, aFile)
filePath = os.path.normpat h(filePath)
cache.write("%s \n" % filePath)
cache.close()

try:
if sys.argv[1] == "-u":
cache()
