Use a modified variable in bash script, trying to change git branch programatically

I’m playing around with my custom commands, and I’m currently trying to change a remote Git branch programatically using bash.

issue() {
    if [ `git branch --list issue_$1` ]
    then
        git checkout issue_$1
    else
        git checkout -b issue_$1
        git branch -u origin issue_${1}
    fi
}

The idea is this function will try to find the branch issue_X, if it does it switches, otherwise it creates and sets the remote origin.

The problem is git branch -u origin issue_${1} I don’t know how to do this, and I’m having trouble googling for it because I don’t know what this process is called.

Thanks a lot for the help!

I don’t know how to do git branch -u origin issue_${1}

If a remote-tracking branch origin/issue_${1} exists you can do git branch -u origin/issue_${1}.

The problem is that in your situation the remote-tracking branch doesn’t exit and you have to create it:

git push -u origin issue_${1}
