status

This command displays information about service.

Interface

status [ -h ] [ -n ] [ -o name,intree,status,... ] [ -g ] [ -d depth ] [ -r ] [ -p nline ] service

By default the dependency graph is rendered in the start order of execution. You can reverse the rendered order, meaning the stop execution, with the -r option.

Without specifying the -o, all fields are displayed.

Options

• -h: prints this help.

• -n: do not display the field name(s) specified. Combining this options with the -o facilitates scripting usage.

• -o: comma separated list of fields to display.

• -g: shows the dependency list of the service as a hierarchical graph instead of a list.

• -d depth: limits the depth of the dependency list visualisation; default is 1. This implies -g option.

• -r: shows the dependency list of services in reverse mode.

• -p nline: prints the nline last lines from the log file of the service. Default is 20.

Valid fields for -o options

• name: displays the name.
• version: displays the version of the service.
• intree: displays the service's tree name.
• status: displays the status.
• type: displays the service type.
• description: displays the description.
• partof: displays the module name for services part of that module.
• notify: displays the number of the fd for readiness notification.
• maxdeath: displays the number of maximum death.
• earlier: displays if service is an earlier one.
• source: displays the source of the service's frontend file.
• live: displays the service's live directory.
• depends: displays the service's dependencies.
• requiredby: displays the service(s) which depends on service.
• contents: displays services within module.
• optsdepends: displays the service's optional dependencies. Also displays the name of the associated tree of the optional dependencies after the colon(:) mark if any.
• start: displays the service's start script.
• stop: displays the service's stop script.
• envat: displays the source of the environment file.
• envfile: displays the contents of the environment file.
• logname: displays the logger's name.
• logdst: displays the logger's destination.
• logfile: displays the contents of the log file.

Usage examples

Displays all information of service foo

66 status foo

Only displays the field name and status of service foo

66 status -o name,status foo

Also, do not display the name of the field name and status of service foo

66 status -no name,status foo

Only displays the contents of the log file of the service foo

66 status -o logfile foo

Also, displays the last 100 lines of the log file of the service foo

66 status -o logfile -p100 foo

In a script you can do

#!/bin/sh

service="${1}"
type=$(66 status -no type ${service})

if [ ${type} = "classic" ]; then
    echo ${service} is a classic service
else if [ ${type} = "module" ]; then
    echo ${service} is a module service
else if [ ${type} = "oneshot" ]; then
    echo ${service} is a oneshot service
fi

Displays information of the service using the graph mode
