The problem is

Quote:
search_proc () {

outputfile3=$3
clear
echo 'Type Proccess name to search for then press ENTER '
ps -ewwo pid,args | grep $outputfile3 | awk '{print $1, $2}'
}
I need it too go from the main menu by pressing 6, to the submenu search_proc. In the search_proc menu/section it need to accept a variable and search the processes for it and sort by PID and Process name. I'm stuck and ran out of ideas. I also cannot figure out why it keeps flashing quick and going back to the main menu.

Inside a function positional parameters are setted with new values, so your $outputfile is null:

Code:
#!/bin/sh
# Usage: ./this_script a b

f() {
  echo $1 $2
}

echo $1 $2

f x

I hope you get the idea.

I'm still confused to be honest. I need it to change to the new menu, then accept the input so i can use it for my grep command.
