concurrent.sh

https://github.com/themattrix/bash-concurrent

A Bash function to run tasks in parallel and display pretty output as they complete.

Rather than showing the output of the programs it runs, it stuffs them into .logs/<timestamp>

One thing it has that I like and would like to steal for crun (or a successor? Is that just a port and shouldn't add functionality?) is a notion of task dependencies:

(Thought: should that be a separate tool? dep specifies a dependency tree, then runs the tasks it needs with crun if necessary or just by themselves? Is that just make?)

Start the medium task after the short task succeeds:

concurrent \
    - 'My long task'   sleep 10 \
    - 'My medium task' sleep 5  \
    - 'My short task'  sleep 1  \
    --require 'My short task'   \
    --before  'My medium task'

Its method of providing names is interesting, though it requires some acrobatics around the - specifier.
