If I start a process with an ampersand (&) at the end, it'll be forked to background. When it finishes, I get an output similar to
+ Fertig my_script
I have a localized distribution, but this shouldn't matter.
What I see is the job ID in square brackets followed by a plus (+).
If I have multiple jobs started in parallel, I get
- Fertig my_script + Fertig my_script
Now I have a minus (-) for the fist job and a plus (+) for the second one.
I wonder, what those +/- mean.
Couldn't find any answer using internet search engines.
