[fpc-devel] Linux Binary - Socket Output affected by SystemCtl, HELP!

[Ozz Nixon]

using the .sh concept:
# systemctl status coderunner
* coderunner.service - The Modern Pascal Code Running Socket Server
   Loaded: loaded (/usr/lib/systemd/system/coderunner.service; enabled;
vendor preset: disabled)
   Active: active (running) since Wed 2020-01-29 10:55:30 EST; 8s ago
  Process: 18065 ExecStartPre=/usr/bin/rm -f /run/coderunner2.pid
(code=exited, status=0/SUCCESS)
 Main PID: 18066 (coderunner2.sh)
   CGroup: /system.slice/coderunner.service
           |-18066 /bin/sh /usr/local/bin/coderunner2.sh
           `-18069 /usr/local/bin/coderunner2

So it starts - telnet 127.0.0.1 - and I get the ???? stuff still.
cat /etc/test.txt
<null>
ls -alrt /etc/test.txt
-rw-r--r-- 1 root root 0 Jan 29 10:54 /tmp/test.txt

chmod 777 just incase...
do not make a different, I even tried, bash, and even added starting...
#!/bin/bash
echo "Starting">>/tmp/test.txt
echo "LANG=$LANG" >>/tmp/test.txt
echo "LOCALE=$LOCALE" >>/tmp/test.txt
export LC_ALL=C
/usr/local/bin/coderunner2

Nothing writes to the file when systemctl starts it. However, if I
./coderunner2.sh I get:
Starting
LANG=en_US
LOCALE=

So, I guess try FPC 3.0.x???
