Hi RudiC,

I'm not sure what you mean? The LINK variable is defined from this line in the script.

Code:
LINK=`cat $TEMP_DIR/test_xml.out | grep link | sed 's/<link>//g;s/<\/link>//g'| awk '{sub(/^[ \t]+/, ""); print}'`

Once the script finishes running (albeit with the 503 service available error) I am able to define the LINK variable from the command line and run the curl GET using $LINK or using the variables contents - either way it works when I run it outside of the script.

If I echo the $LINK variable within the script to get it's contents it is what I expect it to be.

networkctl

NETWORKCTL(1)							    networkctl							     NETWORKCTL(1)

NAME

       networkctl - Query the status of network links

SYNOPSIS

       networkctl [OPTIONS...] COMMAND [LINK...]

DESCRIPTION

       networkctl may be used to introspect the state of the network links as seen by systemd-networkd. Please refer to systemd-
       networkd.service(8) for an introduction to the basic concepts, functionality, and configuration syntax.

OPTIONS

       The following options are understood:

       -a --all
	   Show all links with status.

       -h, --help
	   Print a short help text and exit.

       --version
	   Print a short version string and exit.

       --no-legend
	   Do not print the legend, i.e. column headers and the footer with hints.

       --no-pager
	   Do not pipe output into a pager.

COMMANDS

       The following commands are understood:

       list [LINK...]
	   Show a list of existing links and their status. If no further arguments are specified shows all links, otherwise just the specified
	   links. Produces output similar to:

	       IDX LINK 	TYPE	 OPERATIONAL SETUP
		 1 lo		loopback carrier     unmanaged
		 2 eth0 	ether	 routable    configured
		 3 virbr0	ether	 no-carrier  unmanaged
		 4 virbr0-nic	ether	 off	     unmanaged

	       4 links listed.

       status [LINK...]
	   Show information about the specified links: type, state, kernel module driver, hardware and IP address, configured DNS servers, etc.

	   When no links are specified, an overall network status is shown. Also see the option --all.

	   Produces output similar to:

		     State: routable
		    Address: 10.193.76.5 on eth0
			     192.168.122.1 on virbr0
			     169.254.190.105 on eth0
			     fe80::5054:aa:bbbb:cccc on eth0
		    Gateway: 10.193.11.1 (CISCO SYSTEMS, INC.) on eth0
			DNS: 8.8.8.8
			     8.8.4.4

       lldp [LINK...]
	   Show discovered LLDP (Link Layer Discovery Protocol) neighbors. If one or more link names are specified only neighbors on those
	   interfaces are shown. Otherwise shows discovered neighbors on all interfaces. Note that for this feature to work, LLDP= must be turned
	   on on the specific interface, see systemd.network(5) for details.

	   Produces output similar to:

	       LINK		CHASSIS ID	  SYSTEM NAME	   CAPS        PORT ID		 PORT DESCRIPTION
	       enp0s25		00:e0:4c:00:00:00 GS1900	   ..b........ 2		 Port #2

	       Capability Flags:
	       o - Other; p - Repeater;  b - Bridge; w - WLAN Access Point; r - Router;
	       t - Telephone; d - DOCSIS cable device; a - Station; c - Customer VLAN;
	       s - Service VLAN, m - Two-port MAC Relay (TPMR)

	       1 neighbors listed.

       label
	   Show numerical address labels that can be used for address selection. This is the same information that ip-addrlabel(8) shows. See RFC
	   3484[1] for a discussion of address labels.

	   Produces output similar to:

	       Prefix/Prefixlen 			 Label
		       ::/0				     1
