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

The single equal is correct

string1 == string2

string1 = string2

True if the strings are equal. ‘=’ should be used with the test command for POSIX conformance

NAME="rafael"
USER="rafael"
if [ "$NAME" = "$USER" ]; then
    echo "Hello"
