NAME¶
systemd-activate - Test socket activation of daemonsSYNOPSIS¶
/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¶
--help, -hPrints a short help text and exits.
--version
Prints a short version string and exits.
-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],
--environment=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.
ENVIRONMENT VARIABLES¶
$LISTEN_FDS, $LISTEN_PIDSee sd_listen_fds(3).
$SYSTEMD_LOG_TARGET, $SYSTEMD_LOG_LEVEL,
$SYSTEMD_LOG_COLOR, $SYSTEMD_LOG_LOCATION
Same as in systemd(1).
