Hi there,
We have been given a bit of coursework using awk on html pages. Without giving too much away and risking the wrath of the plagerism checks, I can say we need to deal with certain html elements.
There may be several of these elements on one line. My question is, if there are more... (1 Reply)

Hi All,

systemd-notify
SYSTEMD-NOTIFY(1) systemd-notify SYSTEMD-NOTIFY(1)NAME
systemd-notify - Notify init system about start-up completion and other daemon status changes
SYNOPSIS
systemd-notify [OPTIONS...] [VARIABLE=VALUE...]
DESCRIPTION
systemd-notify may be called by daemon scripts to notify the init system about status changes. It can be used to send arbitrary
information, encoded in an environment-block-like list of strings. Most importantly it can be used for start-up completion notification.
This is mostly just a wrapper around sd_notify() and makes this functionality available to shell scripts. For details see sd_notify(3).
The command line may carry a list of environment variables to send as part of the status update.
Note that systemd will refuse reception of status updates from this command unless NotifyAccess=all is set for the service unit this
command is called from.
OPTIONS
The following options are understood:
--h, --help
Prints a short help text and exits.
--version
Prints a short version string and exits.
--ready
Inform the init system about service start-up completion. This is equivalent to systemd-notify READY=1. For details about the semantics
of this option see sd_notify(3).
--pid=
Inform the init system about the main PID of the daemon. Takes a PID as argument. If the argument is omitted the PID of the process
that invoked systemd-notify is used. This is equivalent to systemd-notify MAINPID=$PID. For details about the semantics of this option
see sd_notify(3).
--status=
Send a free-form status string for the daemon to the init systemd. This option takes the status string as argument. This is equivalent
to systemd-notify STATUS=.... For details about the semantics of this option see sd_notify(3).
--booted
Returns 0 if the system was booted up with systemd, non-zero otherwise. If this option is passed no message is sent. This option is
hence unrelated to the other options. For details about the semantics of this option see sd_booted(3).
--readahead=
Controls disk read-ahead operations. The argument must be a string, and either "cancel", "done" or "noreplay". For details about the
semantics of this option see sd_readahead(3).
EXIT STATUS
On success 0 is returned, a non-zero failure code otherwise.
EXAMPLE
Example 1. Start-up Notification and Status Updates
A simple shell daemon that sends start-up notifications after having set up its communication channel. During runtime it sends further
status updates to the init system:
#!/bin/bash
mkfifo /tmp/waldo
systemd-notify --ready --status="Waiting for data..."
while : ; do
read a < /tmp/waldo
systemd-notify --status="Processing $a"
# Do something with $a ...
systemd-notify --status="Waiting for data..."
done
