Bash man
lists under set
subsection the option -m
described so:
Monitor mode. Job control is enabled. This option is on by default for interactive shells on systems that support it (see JOB CONTROL above). Background processes run in a separate process group and a line containing their exit status is printed upon their completion.
(To find it on the linked page, search for 'monitor mode', there's only one hit.)
The question is whether this mode can be effectively turned off during a bash session, how, and with what expected results? I've been trying to experiment, but so far fruitlessly.
I know the command set +m
, but what is it supposed to cause? Turning off the job control? Silencing the job completion and termination messages?
