Question

I’m writing a Bash script, and I want to checkout a tag and then checkout back to where I started.

I tried git co HEAD@{1}, but when starting at master, that takes me back to the commit SHA of master but with a detatched head.

Is there something like pushd & popd for Git?

Answer 1

git checkout @{-1} which can be abbreviated to git checkout -.

From the manpage:

As a special case, the “@{-N}” syntax
for the N-th last branch checks out
the branch (instead of detaching). You
may also specify – which is synonymous
with “@{-1}”.
