Determine if directory is under git control

Question

How can I tell if a given directory is part of a git respository?

(The following is in python, but bash or something would be fine.)

os.path.isdir(\'.svn

Using git rev-parse --is-inside-work-tree along with subprocess.Popen, you can check if "true" is printed from the output indicating the directory does have a git repo:

import subprocess

repo_dir = "../path/to/check/" 

command = ['git', 'rev-parse', '--is-inside-work-tree']
process = subprocess.Popen(command, stdout=subprocess.PIPE, cwd=repo_dir,
                           universal_newlines=True)
process_output = process.communicate()[0]

is_git_repo = str(process_output.strip())

if is_git_repo == "true":
    print("success! git repo found under {0}".format(repo_dir))
else:
    print("sorry. no git repo found under {0}".format(repo_dir))
