This is what i've got so far..

Code:

#!/bin/sh
  
  case "$1" in
    start)
	while : ; do
            ./pager.sh &&
            sleep 30
            ./pager99.sh &&

                if [ -f "pagemod.txt" ]
                then
                    :
                else
                    echo "The pagemod text was not generated during loop!"
                fi
                if [ -f "pagemod0.txt" ]
                then
                    :
                else
                    echo "The pagemod0 text was not generated during loop!"
                fi

As far as using relative paths you make a point but i don't intend on moving them besides i want them to break if they do get copied elsewhere. As far as the background process issue, I do want them to complete so I added the extra but I would like to see an example of the wait command. I don't think i've ever used that yet. With the extra & I wonder if the script will run slower although speed is not of the utmost importance. Converted the idles. At first you lost me with the wrapper idea but i think i get it.. is it if I contain the loop, then for stopping the process it'll make it easier for the parent script?
