Hi, you can use the "read" command with -t option. This would help. Please find the code below.

Code:

#! /bin/sh

echo ""
echo "Program starts..."
echo "Enter the value within 10 seconds..."

read -t 10 input [COLOR=Blue]# Here -t followed by 10 means, the command will wait for 10 seconds to get the input.[/COLOR]

if [ -z $input ]
then
    echo "Timed out. Please try again..."
else
    echo "Successfully logged in..."
fi
echo ""
