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).
EXAMPLE 1
$ /usr/lib/systemd/systemd-activate -l 2000 -a cat
This runs an echo server on port 2000.
EXAMPLE 2
$ /usr/lib/systemd/systemd-activate -l 19531 /usr/lib/systemd/systemd-journal-gatewayd
This runs a socket activated instance of systemd-journal-gatewayd(8).
