NAME

       readproctitle - maintains an automatically rotated log in memory for inspection by ps(1).

       readproctitle is available in daemontools 0.75 and above.

SYNOPSIS

       readproctitle L D

DESCRIPTION

       L consists of any number of arguments.  D is one argument consisting of at least five dots.

       readproctitle  reads  data  into  the  end  of  D,  shifting D to the left to make room. This means that the most recent data is visible to
       process-listing tools such as ps(1).  readproctitle always leaves three dots at the left of D.

       For example, if

	readproctitle io errors: ....................

       reads the data

	fatal error xyz
	warning abc

       then its command-line arguments change to

	readproctitle io errors: ... xyz!warning abc!

       with a newline character in place of each !. Process-listing tools typically show the newline character as ? or 
.

       readproctitle exits when it reaches the end of input.

       Beware that most implementations of ps(1) have small argument-length limits. These limits apply to the total length of readproctitle  L	D.
       I have not seen a system with a limit below 512 bytes.

update-service(8)					      System Manager's Manual						 update-service(8)

NAME

       update-service - add/remove a service to/from system-wide service supervision

SYNOPSIS

       update-service --add|--remove service-directory [service-name]

       update-service --list|--check [service-name]

DESCRIPTION

       service-directory must be a directory to be used by supervise(8), service-name must not start with a dot, and must not contain a slash.

       update-service  adds or removes the service-directory to the system-wide service supervision provided through daemontools' svscan(8), lists
       all registered system-wide services, or checks for a specific service-name whether it is registered.

       When adding a service, and the service-directory resides in /etc/, update-service makes sure that the ./supervise/  subdirectories  in  the
       service-directory,  and	the optional service-directory/log/, are symbolic links pointing into /var/lib/supervise/, unless they already are
       symbolic links.

OPTIONS

       --add | -a
	      Add the service directory service-directory to the system-wide service supervision, under the name service-name.	If service-name is
	      not specified, update-service will use the basename of service-directory.  You can use the svc(8) program to control the newly added
	      service, and the svstat(8) program to query its status, e.g.:

	      # svstat /etc/service/service-name

       --remove | -r
	      Remove the service directory service-directory, which has been added under the  name  service-name,  from  the  system-wide  service
	      supervision.   If  service-name is not specified, update-service will use the basename of service-directory.  When removing the ser-
	      vice-directory, the exit command is sent to the corresponding supervise(8) process, telling it to take the  service  down  and  exit
	      afterwards.  You can use the svc(8) and svstat(8) programs to control the removed service, or query its status, e.g.:

	      # svstat service-directory

       --list | -l
	      If  service-name is specified, update-service checks whether service-name is registered as system-wide service, prints a message and
	      exits non-zero if not, or prints the service-name and the directory it points to and exits zero if  yes.	 If  service-name  is  not
	      specified, it prints the names of all system-widely registered services, one per line.

       --check | -c
	      The same as --list, but update-service doesn't print anything to standard out or standard error.

ENVIRONMENT

       SVDIR  The environment variable $SVDIR overrides the default services directory /etc/service/.

FILES

       /etc/service/
