Git list of remote branches

Question

I'm looking for the best way to execute a function for each Git remote branch in a PowerShell script.

I don't know the best way to get a list of Git remote branches. I can successfully list all remote branches, but I always end up with pesky formatting in the branch names.

Here are the commands I've tried and the resulting arrays I've gotten.

$allBranches = git branch -r
$allBranches = @('  origin/branch1', '  origin/branch2', '  origin/branch3')

$allBranches = git for-each-ref --shell --format=%(refname) refs/remotes/origin
$allBranches = @(''origin/branch1'', ''origin/branch2'', ''origin/branch3'')

I would like $allBranches = @('origin/branch1', 'origin/branch2', 'origin/branch3'), so my current approach is to just manually remove formatting from the weird branch names using Trim():

foreach($branch in $allBranches) {
    # Format $branch
    # Do function
}

Is there a better approach?

Answer 1

The Trim() operation should do what you want.

$allTrimmedBranches = @()
foreach($branch in $allBranches) {
    $allTrimmedBranches += $branch.Trim()
}
#do function

Answer 2

$branches = git for-each-ref --format='%(refname:short)' refs/remotes/origin
