bazaar branch fails

[Rahul Nabar]

While using bazaar to version scripts on my Linux box frequently I
come across a script that I want to enhance. Say script.sh

I'd prefer working on a development version till I'm sure it works and
then I can safely unleash it on my users. I thought this was a good
(albeit trivial perhaps) spot to use bzr branch.

I tried:

bzr add script.sh
bzr commit script.sh
bzr branch script.sh script.sh.devel

bzr: ERROR: Not a branch: "home/user/xxx/yyy/code/"

Is this a wrong spot to use branch? Or am I not using the correct syntax?

Any suggestions?
