.SH SYNOPSIS
|
||
|
|
.B runsvdir
|
||
|
|
[\-P]
|
||
|
|
.I dir
|
||
|

[

|

.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.
