SYSTEMD-ACTIVATE(8)            systemd-activate            SYSTEMD-ACTIVATE(8)

NAME
       systemd-activate - Test socket activation of daemons
SYNOPSIS
       /usr/lib/systemd/systemd-activate [OPTIONS...] daemon [OPTIONS...]
DESCRIPTION
       systemd-activate can be used to launch a socket activated daemon from
       the command line for testing purposes. It can also be used to launch
       single instances of the daemon per connection (inetd-style).
       The daemon to launch and its options should be specifed after options
       intended for systemd-activate.
       If the -a option is given, file descriptor of the connection will be
       used as the standard input and output of the launched process.
       Otherwise, standard input and output will be inherited, and sockets
       will be passed through file descriptors 3 and higher. Sockets passed
       through $LISTEN_FDS to systemd-activate will be passed through to the
       dameon, in the original positions. Other sockets specified with
       --listen will use consecutive descriptors.
OPTIONS
       -l address, --listen=address
           Listen on this address. Takes a string like "2000" or
           "127.0.0.1:2001".
       -a, --accept
           Launch a separate instance of daemon per connection and pass the
           connection socket as standard input and standard output.
       -E VAR[=VALUE], --setenv=VAR[=VALUE]
           Add this variable to the environment of the launched process. If
           VAR is followed by "=", assume that it is a variable-value pair.
           Otherwise, obtain the value from the environment of
           systemd-activate itself.
       -h, --help
           Print a short help text and exit.
       --version
           Print a short version string and exit.
ENVIRONMENT VARIABLES
       $LISTEN_FDS, $LISTEN_PID
           See sd_listen_fds(3).
       $SYSTEMD_LOG_TARGET, $SYSTEMD_LOG_LEVEL, $SYSTEMD_LOG_COLOR,
       $SYSTEMD_LOG_LOCATION
           Same as in systemd(1).
EXAMPLES
       Example 1. Run an echo server on port 2000
           $ /usr/lib/systemd/systemd-activate -l 2000 -a cat
       Example 2. Run a socket activated instance of systemd-journal-
       gatewayd(8)
           $ /usr/lib/systemd/systemd-activate -l 19531 /usr/lib/systemd/systemd-journal-gatewayd
