Of course. You would write the last line as

   echo "$branchName"

These are shell fundamentals.

If you want to do that in a script, this is not a work-around, but it is 
how you should do it. But you may want to use option --short to save the 
second line.

Try

   branchName=$(git rev-parse --abbrev-ref HEAD)
