git branch for multiple remotes

When running git branch -r I see the branches on my remote repository. Is there a way to see in the same working directory, the branches of multiple repositories? My goal is to create a file that lists all branches in couple of repositories, like this:

repo1:master,dev,qa,fy-2473
repo2:master,dev,fy-1128,staging
repo3:master,fy-1272,staging

So on and so forth. I have this to print the branches the right way:

git branch -r | awk -F' +|/' -v ORS=, '{if($3!="HEAD") print $3}' >> repolist.txt

I just need to have this functionality work with couple of repositories without having to clone each and everyone of them for this single purpose. Thanks.

Add your repos as remotes to your local repo with git remote add, then git fetch --all them and adapt your awk command to produce the result you want.

This command will produce the output you expect

git branch -r | awk '
    # split remote and branch
    {
        remote = substr($1, 0, index($1, "/") - 1)
        branch = substr($1, index($1, "/") + 1)
    }

    # eliminate HEAD reference
    branch == "HEAD" { next }

    # new remote found
    remote != lastRemote {
        # output remote name
        printf "%s%s:", lastRemote ? "\n" : "", remote
        lastRemote = remote
        # do not output next comma
        firstBranch = 1
    }

    # output comma between branches
    !firstBranch { printf "," }
    firstBranch { firstBranch = 0 }

    # output branch name
    { printf branch }

    # final linebreak
    END { print "" }
'

or as one-liner without comments

git branch -r | awk '{ remote = substr($1, 0, index($1, "/") - 1); branch = substr($1, index($1, "/") + 1) } branch == "HEAD" { next } remote != lastRemote { printf "%s%s:", lastRemote ? "\n" : "", remote; lastRemote = remote; firstBranch = 1; } !firstBranch { printf "," } firstBranch { firstBranch = 0 } { printf branch } END { print "" }'

After you run git remote add to add all remote repositories, and run git fetch to retrieve / update information of remote repositories, git branch -a will show all branches, both remote and local. For remote branches, it will be shown in format as:

remotes/{remote_name}/{branch_name}

You can add the repositories to the same working directory using git remote add name url, then you will see all of them when you do git branch -r.

For instance:

git remote add repo1 http://github.com/example/foo.git
git remote add repo2 http://bitbucket.com/example/bar.git
git fetch --all
git branch -r

will list:

repo1/master
repo1/dev
repo2/master
repo2/featureXYZ
