How can I search Git branches for a file or directory?

git log + git branch will find it for you:

% git log --all -- somefile

    added somefile


% git branch -a --contains 55d2069
  otherbranch

Supports globbing, too:

% git log --all -- '**/my_file.png'

The single quotes are necessary (at least if using the Bash shell) so the shell passes the glob pattern to git unchanged, instead of expanding it (just like with Unix find).

git ls-tree might help. To search across all existing branches:

for branch in `git for-each-ref --format="%(refname)" refs/heads`; do
  echo $branch :; git ls-tree -r --name-only $branch | grep '<foo>'
done

The advantage of this is that you can also search with regular expressions for the file name.

Although ididak's response is pretty cool, and Handyman5 provides a script to use it, I found it a little restricted to use that approach.

Sometimes you need to search for something that can appear/disappear over time, so why not search against all commits? Besides that, sometimes you need a verbose response, and other times only commit matches. Here are two versions of those options. Put these scripts on your path:

git-find-file

for branch in $(git rev-list --all)
do
  if (git ls-tree -r --name-only $branch | grep --quiet "$1")
  then
     echo $branch
  fi
done

git-find-file-verbose

for branch in $(git rev-list --all)
do
  git ls-tree -r --name-only $branch | grep "$1" | sed 's/^/'$branch': /'
done

Now you can do

$ git find-file <regex>
sha1
sha2

$ git find-file-verbose <regex>
sha1: path/to/<regex>/searched
sha1: path/to/another/<regex>/in/same/sha
sha2: path/to/other/<regex>/in/other/sha

See that using getopt you can modify that script to alternate searching all commits, refs, refs/heads, been verbose, etc.

$ git find-file <regex>
$ git find-file --verbose <regex>
$ git find-file --verbose --decorated --color <regex>
