Background Process (bg)

Run processes in the background

Description

bg supports two modes: it can either be run as a function block which will execute in the background, or it can take stopped processes and daemonize them.

Usage

POSIX only:

bg { code block }

bg fid

Examples

bg { sleep 5; out "Morning" }

Detail

The examples above will work on any system (Windows included). However the ctrl+z usage of backgrounding a stopped process (like Bash) is only supported on POSIX systems due to the limitation of required signals on non-platforms. This means the usage described in the examples is cross cross platform while bg int currently does not work on Windows nor Plan 9.
