rerun is a tiny little script that helps you run repetetive shell commands
over and over again.
Imagine you're working on debugging an issue with a particular daemon, like Celery. In one window you're editing code to try solutions, and in another you're stopping and starting the Celery and RabbitMQ daemons.
The commands you're running over and over in varying order might look like this:
sudo /etc/init.d/rabbitmq-server restart sudo /etc/init.d/celeryd stop sudo /etc/init.d/celeryd start tail /var/log/celery/myhost.log tail /var/log/celery/myotherhost.log
Running the various commands can be a pain. They're similar enough that tab
completion, zsh's history completion, and
Ctrl-R searching all fall short.
rerun comes in:
curl 'http://bitbucket.org/sjl/src/tip/rerun' > /usr/local/bin/rerun chmod a+x /usr/local/bin/rerun
When you run
rerun you're greeted with a prompt like this:
Type /help (or just /h) to get a list of commands:
> /help (/a)dd [command] (/d)elete [key] (/h)elp (/q)uit >
Add commands to the list with /add. You can specify the command right in the
/add command or let
rerun prompt you for it:
> /add ls [a] ls > /add Enter command: pwd [a] ls [b] pwd >
Now that you've got some commands in the list, run them by entering the key displayed next to their name:
[a] ls [b] pwd > a LICENSE.markdown README.markdown rerun [a] ls [b] pwd > b /Users/sjl/src/rerun [a] ls [b] pwd >
If you don't need a command any more you can /delete it:
[a] ls [b] pwd > /delete b [a] ls > /d Which command? a >
Use /quit or
Ctrl-D to exit.
