.TH runsvdir 8
.SH NAME
runsvdir \- starts and monitors a collection of runsv(8) processes
.SH SYNOPSIS
.B runsvdir
[\-P]
.I dir
[
.I log
]
.SH DESCRIPTION
.I dir
must be a directory.
.I log
is a space holder for a readproctitle log, and must be at least seven
characters long or absent.
.P
.B runsvdir
starts a
.BR runsv (8)
process for each subdirectory, or symlink to a directory, in the services
directory
.IR dir ,
up to a limit of 1000 subdirectories,
and restarts a
.BR runsv (8)
process if it terminates.
.B runsvdir
skips subdirectory names starting with dots.
.BR runsv (8)
must be in
.BR runsvdir 's
PATH.
.P
At least every five seconds
.B runsvdir
checks whether the time of last modification, the inode, or the device, of
the services directory
.I dir
has changed.
If so, it re-scans the service directory, and if it sees a new subdirectory,
or new symlink to a directory, in
.IR dir ,
it starts a new
.BR runsv (8)
process;
if
.B runsvdir
sees a subdirectory being removed that was previously there, it sends the
corresponding
.BR runsv (8)
process a TERM signal, stops monitoring this process, and so does not
restart the
.BR runsv (8)
process if it exits.
.P
If the
.I log
argument is given to
.BR runsvdir ,
all output to standard error is redirected to this
.IR log ,
which is similar to the daemontools'
.B readproctitle
log.
To see the most recent error messages, use a process-listing tool such as
.BR ps (1).
.B runsvdir
writes a dot to the readproctitle log every 15 minutes so that old error
messages expire.
.SH OPTIONS
.TP
.B \-P
use
.BR setsid (2)
to run each
.BR runsv (8)
process in a new session and separate process group.
.SH SIGNALS
If
.B runsvdir
receives a TERM signal, it exits with 0 immediately.
.P
If
.B runsvdir
receives a HUP signal, it sends a TERM signal to each
.BR runsv (8)
process it is monitoring and then exits with 111.
