Tilde expansion seems to have some oddities surrounding it. Not a satisfying answer, because it doesn't solve the real problem, but this seems to work:
I'm having problems with bash scripts. If a bash script is called with no arguments, I always get "PHIST=!" as the first argument (i.e. this is what $1 equals). Why? Where does this come from, and how can I fix it? Nothing in the bash man pages refer to this mysterious default argument. (2 Replies)

systemd-activate
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 --help, -h
Prints 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_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).
