Linux shell programming string compare syntax

Question

What is the difference between = and == to compare strings in Linux shell programming?

Maybe the following code works:

if [ \"$         


        

Answer 1

you can take a look here or here. Personally, to compare strings, I use case

case "$string1" in
  "$string2" ) echo "matched";;
  *) echo "not matched";;
esac

I do not have to know which operator i should use
