If you work with Gerrit you use its CLI tool git review.
Working with OpenStack, I use it a lot every day. I need to update the last
patch and send it to the Gerrit very often. That’s why I created one line
script to execute git commit -a --amend && git review command.
I put it into the /usr/local/bin/git-review-update file with a following
content:
#!/bin/sh
git commit -a --amend && git review
Now, I can use git review-update command to update the last patch and send it
to Gerrit. It’s a good example of the simplest and fastest solutions which
works for me during the last two years. Of course, I have to read
Contributing guide
and propose a new command to git-review at some point.
