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         


        

Answer 1

For the record, use git status or similar, this is just for completeness: :)

Searching upward a tree is no biggie really, in bash you can do this simple one-liner (if you put it on one line...) ;) Returns 0 if one is found, 1 otherwise.

d=`pwd`
while [ "$d" != "" ]; do
  [ -d "$d"/.git ] && exit 0
  d=${d%/*}
done
exit 1

will search upward looking for a .git folder.
