Together

together can run multiple processes, together, such as that they live and die together. It is useful in the case you have a a supervising process that watches a single PID. This can be specifically interesting for container runtimes that expect a single process to run.

It is in a way an 'anti-supervisor' it doesn't restart processes but rather makes sure that all processes die together.

Usage

together "long running process 1" "long running process 2" "another long running process"

For example:

together "sleep 5" "sleep 10"

Will spawn two processes, when the first one exits after 5 seconds its sibling will be killed too.

• If any of the processes die, together will kill the others
• If it receives a SIGTERM or a SIGINT it will kill the spawned processes

Compiling

together is written in crystal, so you will need that installed, afterwards:

crystal build together.cr

Installation

For the moment, grab the executable built with the github action :

wget https://github.com/OriPekelman/together/releases/download/v0.11/together
