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