Track all remote git branches as local branches

Question

Tracking a single remote branch as a local branch is straightforward enough.

$ git checkout --track -b ${branch_name} origin/${branch_name}

Update Q1 2020: Mohsen Abasi proposes in the comments, based on the 2014 slm's answer, the simpler alternative:

for i in $(git branch -r | grep -vE "HEAD|master" | sed 's/^[ ]\+//'); 

And it uses $() instead of obsolete backticks.

As I mention in another old answer, using git for-each-ref is probably faster.
And I would use the new (Git 2.23+) git switch command, which replaces the confusing git checkout.

for i in $(git for-each-ref --format=%(refname:short) \
  --no-merged=origin/HEAD refs/remotes/origin); do \
    git switch --track $i; \
done

That way, no grep needed.

Old (2011) original answer:

Here is my one-liner I use (in a bash shell, tested with msysgit1.7.4):

For copy-paste:

remote=origin ; for brname in `git branch -r | grep $remote | grep -v master | grep -v HEAD | awk '{gsub(/^[^\/]+\//,"",$1); print $1}'`; do git branch --set-upstream-to $remote/$brname $brname; done

For more readability:

remote=origin ; // put here the name of the remote you want
for brname in `
    git branch -r | grep $remote | grep -v master | grep -v HEAD 
    | awk '{gsub(/^[^\/]+\//,"",$1); print $1}'
`; do 
    git branch --set-upstream-to $remote/$brname $brname; 
done

• it will only select upstream branches from the remote you specify in the remote variable (it can be 'origin' or whatever name you have set for one of the remotes of your current Git repo).
• it will extract the name of the branch: origin/a/Branch/Name => a/Branch/Name through the awk expression.

• it will set the upstream branch through --set-upstream-to (or -u), not --track:
  The advantage is that, if the branch already exists, it won't fail and it won't change that branch origin, it will only configure the branch.xxx.(remote|merge) setting.

  branch.aBranchName.remote=origin
  branch.aBranchName.merge=refs/heads/a/Branch/Name
  

That command will create local branches for all remote upstream branches, and set their remote and merge setting to that remote branch.
