Tools Bash - How to do a "read -p" inside a while loop?
Hi there guys!

I was trying to do:

Code:
while read line; do
if [ $cont -eq 5 ]; then
   read -p "Press Enter to continue..."
   cont=0
fi

echo $line

let cont++

done < file.txt

However, I have read that the read -p would not work in a while loop...

I was wondering if there is any other way to pause the loop to wait for a key to continue..

I have tried putting the 'read -p "text"' in a function and calling it inside the while loop, also doing 'dd count=1 1>/dev/null 2>&1'... But I've had no luck..

Any help would be greatly appreciated!

Thanks!

Regards,
Rplae.
