I have the following code but I didn’t understand
the [ $val -eq 0 ] 2 part. What does the two (2) there for?
#!/bin/bash
val=0
while [ $val -eq 0 ] 2> /dev/null; do
read -p "Please enter a value: " val
done
echo "You didn't enter 0!"
Cheers,
It means standard error, i.e. redirect any error message to /dev/null which basically means don’t display any error message that would show up in the redirected command.
