service(8) System Manager's Manual service(8)
NAME
service - run a System V init script
SYNOPSIS
service SCRIPT COMMAND [OPTIONS]
service --status-all
service --help | -h | --version
DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
directory set to /.
The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the
invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and
stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start
command.
service --status-all runs all init scripts, in alphabetical order, with the status command.
If the init script file does not exist, the script tries to use legacy actions. If there is no suitable legacy action found and COMMAND is
one of actions specified in LSB Core Specification, input is redirected to the systemctl. Otherwise the command fails with return code 2.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
