Hi,
I am new to shell scripting, started learning script before one month. I can't understand the below script.
dialog --title "Inputbox - To take input from you" --backtitle "Linux Shell\
Script Tutorial" --inputbox "Enter your name please" 8 60 2>/tmp/input.$$
In this script they are redirecting the inputbox value to temporary file. why 2 is used here 2>/tmp/input.$$
Please help me to understand the script
