rerun is a tiny little script that helps you run repetetive shell commands over and over again.

The Problem

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. That's where 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]


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

[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.
