A handy bash script to run almost any programs in the background using the screen command.

screen.sh

#!/bin/bash

function launch(){
     local execbin="`which ${target}`"
     local str="`screen -list "${target}" | egrep 'Detached|Attached' | awk '{print $1}'`"
     ps aux | egrep -v 'grep|ps aux|screen|SCREEN' | grep pts | grep \^${USER} | grep ${target}
     if [ "${str}" != "" ]; then
         echo -e "\"${str}\" is present."
         echo "Reattaching... (ignoring options)"
         sleep 1
         str="`screen -list | grep "${target}" | grep "Attached" | awk '{print $1}'`"
         if [ "${str}" == "" ]; then
             screen -r ${str}
         else
             screen -rx ${str}
         fi
     else
         screen -dmS ${target} ${execbin} "${@}"
         echo -e "Created \"`screen -list | grep "${target}" | awk '{print $1}'`\", running ${target} with PID:`pidof ${target}`."
     fi
}


args0=("${@}")
args1=(`for ((c=1; c<${#args0[@]}; c++)); do echo "${args0[${c}]}"; done`)
target=${args0[0]}
