jack.ctl - JACK Session Manager
jack.ctl is a simple JACK session manager. It reads configuration
information from a system wide and a user specific configuration file
and manages sessions involving the JACK daemon proper and optionally a
set of secondary jack daemons.
The configuration is a list of assignments of the form variable=value.
The variables jackd and driver must be assigned. These set the JACK
daemon to run, normally either jackd(1) or jackstart(1), and the driver
to use, normally alsa.
If the variable jackh is assigned it names a set of secondary daemons,
normally jack.plumbing(1) and jack.clock(1), which are managed together
with the JACK daemon proper. The secondary daemons are started one
second after jackd, in the background, and with no arguments. To name
more than one daemon the list must be quoted using ordinary double
All other variables are optional and are named identically to the long
forms of the options to jackd(1) and have the meanings descibed in that
