How do I control paging in a while loop

[Tison]

This code does not perform the "read answer" command (any ideas ) ? I am trying to page after 20 lines.

while read SRV DATE TIME USER
do printf "| %-8s | %10s | %6s | %6s |\n" $SRV $DATE $TIME $USER
let CNT=$CNT+1
if [[ $CNT -ge 20 ]]
then
echo "Press enter to continue...\c"
read answer
CNT=0
fi
done < tmpfile

The &quot;read answer&quot; line is getting its input from the same place the &quot;while read&quot; loop control is getting its input.

My suggestion would be to remove the paging control you've got there, and pipe the output of the entire run through more or less.

Alternatively, you could also write your script to write a child script with 20 iterations of work followed by an iteration of pausing, and so on.
