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.
That's where rerun comes in:
curl 'https://raw.githubusercontent.com/mandarg/rerun/master/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
(/r)run all commands in order shown
>
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
>
You can also run all commands currently in the queue with a /run or /r:
> /run
/home/mandar/sandbox/rerun
LICENSE.markdown README.markdown rerun
[a] pwd
[b] ls
Use /quit or Ctrl-D to exit.
