Parse another script's output

Question

I'd like to do a script which, among other stuff, grabs the output of git branch and gets the selected branch. The typical output would be:

master
develop
* release-1.0
...

And I would want to get:

release-1.0

I guess it could be done using pipes, but I have not a single clue. Could you mates help me with this? Thanks in advance!

Use the plumbing instead:

branch=$(git symbolic-ref HEAD)

git branch's output is considered porcelain and is not recommended for use in scripts.

And massage it with sed to remove the refs/heads portion: sed -e 's,.*/,,'

Whoa, I didn't know that. Could sed be piped too?

line=$(git branch|grep '*')
echo ${line#* }
