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.

SYNOPSIS

       bashbug [--help] [--version] [bug-report-email-addresses]

DESCRIPTION

       bashbug is a utility for reporting bugs in Bash to the maintainers.

       bashbug will start up your preferred editor with a preformatted bug report template for you to fill in. Save the file and quit the editor
       once you have completed the missing fields.  bashbug will notify you of any problems with the report and ask for confirmation before
       sending it. By default the bug report is mailed to both the GNU developers and the Debian Bash maintainers. The recipients can be changed
       by giving a comma separated list of bug-report-email-addresses.

       If you invoke bashbug by accident, just quit your editor. You will always be asked for confirmation before a bug report is sent.

OPTIONS

       --help
	      Show a brief usage message and exit.

       --version
	      Show the version of bashbug and exit.

       bug-report-email-addresses

	      maintainers.

ENVIRONMENT
