I'm nested deep in a file tree, and I'd like to find which parent directory contains a file.

E.g. I'm in a set of nested Git repositories and want to find the .git directory controlling the files I'm currently at. I'd hope for something like find -searchup -iname ".git"

An even more general version that allows using find options:

set -e
shift 1
while [[ "$path" != "/" ]];
    find "$path"  -maxdepth 1 -mindepth 1 "$@"
    # Note: if you want to ignore symlinks, use "$(realpath -s $path/..)"
    path="$(readlink -f $path/..)"

For example (assuming the script is saved as some_dir -iname "foo*bar" -execdir pwd \;

...will print the names of all of some_dir's ancestors (including itself) up to / in which a file with the pattern is found.

When using readlink -f the above script will follow symlinks on the way up, as noted in the comments. You can use realpath -s instead, if you want to follow paths up by name ("/foo/bar" will go up to "foo" even if "bar" is a symlink) - however that requires installing realpath which isn't installed by default on most platforms.

the trouble with these is the way it resolves links. for example if i'm in ~/foo/bar , and bar is a symlink to /some/other/place, then ~/foo and ~/ will never be searched. – Erik Aronesty Jun 5 at 13:07
@ErikAronesty, you're right - updated the answer. You can use realpath -s to get the behaviour you want. – sinelaw Jun 6 at 20:53
that works when you specify a full path to search. sadly, on centos 5.8, realpath -s <dir> has a bug where if <dir> is relative, then it resolves symlinks anyway... despite it's documentation. – Erik Aronesty Jun 8 at 20:17
i posted a version that works using pwd/cd instead – Erik Aronesty Jun 8 at 20:31

I've found that working with symlinks kill some of the other options. Especially the git specific answers. I've halfway created my own favorite out of this original answer that's pretty effecient.

#!/usr/bin/env bash

# usage: upsearch .git

function upsearch () {
    test / == "$PWD" && cd "$origdir" && return || \
    test -e "$1" && echo "$PWD" && cd "$origdir" && return || \
    cd .. && upsearch "$1" "$origdir"

I'm using symlinks for my go projects because go wants source code in a certain location and I like to keep my projects under ~/projects. I create the project in $GOPATH/src and symlink them to ~/projects. So running git rev-parse --show-toplevel prints out the $GOPATH directory, not the ~/projects directory. This solution solves that problem.

I realize this is a very specific situation, but I think the solution is valuable.

If you're using zsh with extended globbing enabled, you can do it with a oneliner:

(../)#.git(:h)   # relative path to containing directory, eg. '../../..', '.'
(../)#.git(:a)   # absolute path to actual file, eg. '/home/you/src/prj1/.git'
(../)#.git(:a:h) # absolute path to containing directory, eg. '/home/you/src/prj1'

Explanation (quoted from man zshexpn):

Recursive Globbing

A pathname component of the form (foo/)# matches a path consisting of zero or more directories matching the pattern foo. As a shorthand, **/ is equivalent to (*/)#.


After the optional word designator, you can add a sequence of one or more of the following modifiers, each preceded by a ':'. These modifiers also work on the result of filename generation and parameter expansion, except where noted.

  • a
    • Turn a file name into an absolute path: prepends the current directory, if necessary, and resolves any use of '..' and '.'
  • A
    • As 'a', but also resolve use of symbolic links where possible. Note that resolution of '..' occurs before resolution of symbolic links. This call is equivalent to a unless your system has the realpath system call (modern systems do).
  • h
    • Remove a trailing pathname component, leaving the head. This works like 'dirname'.

Credits: Faux on #zsh for the initial suggestion of using (../)#.git(:h).

This is amazing... If I could only figure out (hint: you should tell me) what (../) is doing... Oh, and who/what is Faux on #zsh? – alex gray Mar 20 at 15:05
@alexgray (../) alone doesn't mean much, but (../)# means try to expand the pattern inside the parenthesis 0 or more times, and only use the ones that actually exist on the filesystem. Because we're expanding from 0 to n parent directories, we effectively search upwards to the root of the file system (note: you probably want to add something after the pattern to make it meaningful, but for enlightenment execute print -l (../)#). And #zsh is an IRC channel, Faux is a username on it. Faux suggested the solution, therefore the credit. – unthought Mar 22 at 11:03
That will expand all of them. You may want: (../)#.git(/Y1:a:h) to stop at the first found one (with a recent version of zsh) – Stéphane Chazelas Jun 8 at 20:43
Very helpful, thanks. To enable extended globbing do setopt extended_glob – Shlomi Sep 24 at 8:40

This version of findup supports "find" syntax, like @sinelaw's answer, but also support symlinks without needing realpath. It also supports an optional "stop at" feature, so this works: findup .:~ -name foo ... searches for foo without passing the home dir.


set -e

# get optional root dir
IFS=":" && arg=($1)
shift 1
[[ $root ]] || root=/
# resolve home dir
eval root=$root

# use "cd" to prevent symlinks from resolving
cd $path
while [[ "$cur" != "$root" && "$cur" != "/" ]];
    find  "$cur/"  -maxdepth 1 -mindepth 1 "$@"
    cd ..

Find can't do it. I can't think of anything simpler than a shell loop. (Untested, assumes there is no /.git)

git_root=$(pwd -P 2>/dev/null || command pwd)
while [ ! -e "$git_root/.git" ]; do
  if [ "$git_root" = "" ]; then break; fi

For the specific case of a git repository, you can let git do the work for you.

git_root=$(GIT_EDITOR=echo git config -e)

Cool, this puts me on a path for a general solution - which I post as another answer here. – Vincent Scheib Oct 7 '11 at 0:56
I also like the answer being general and not specific to git. – Johann Philipp Strathausen Nov 25 '11 at 13:47

A generalized version of Gilles' answer, first parameter used to find match:

find-up () {
  while [[ "$path" != "" && ! -e "$path/$1" ]]; do
  echo "$path"

Keeps the use of sym-links.

git rev-parse --show-toplevel

will print out the top level directory of the current repository, if you are in one.

Other related options:

# `pwd` is inside a git-controlled repository
git rev-parse --is-inside-work-tree
# `pwd` is inside the .git directory
git rev-parse --is-inside-git-dir

# path to the .git directory (may be relative or absolute)
git rev-parse --git-dir

# inverses of each other:
# `pwd` relative to root of repository
git rev-parse --show-prefix
# root of repository relative to `pwd`
git rev-parse --show-cdup
share|improve this answer
This works only for git itself. The question is more generic. – alex Jan 26 '11 at 7:15
This will not work in a bare repo, – Jason Pyeron Sep 1 '14 at 4:01
