====== Screen Stuff ======

Very useful utility that can be used to run unattended software.

===== Monitoring Software =====

Script to start the monitoring software in screen. **EXEC** is the executable name and **SMON** should contain screen label.

<file bash my1mon.sh>
#!/bin/bash

THATPATH=$(cd $(dirname $0);pwd)
THATNAME="my1mon"
THATEXEC="my1run"

[ ! -d "$THATPATH" ] && exit 1
[ ! -f "${THATPATH}/${THATEXEC}" ] && exit 2

cd "$THATPATH"
screen -wipe >/dev/null
check=`screen -ls | grep "$THATNAME"`
if [ "$check" = "" ] ; then
  echo -n "Creating new screen... "
  screen -d -m -S "$THATNAME"
  echo "done."
fi
check=`screen -ls | grep "$THATNAME"`
if [ "$check" = "" ] ; then
  echo "Screen not found! Aborting!"
  exit 1
else
  echo -n "Starting monitor in screen... "
  screen -S "$THATNAME" -X stuff "./${THATEXEC}^M"
  echo "done."
fi
</file>

To start it every time the system starts, add the following code to startup script (e.g. //rc.local//)
<code bash>su -c 'sh /home/user/mymon/my1mon.sh' - user</code>
