[SOLVED] This shell script is not working, code is right but it gives error each time

Issue

echo "Enter Username"
read name
username = 'hagemaru'
if [ $name == $username ]
  then
    echo "Valid Username"
else
    echo "Entered Username is invalid"
    exit 1
fi
exit 0

Errors while executing:

l.sh: 3: username: not found
l.sh: 4: [: hagemaru: unexpected operator

Output should be:

Valid Username

Solution

You need to remove the space between username and =, otherwise bash will interpret username as a command (as indicated in the error message) which doesn't exist. Doing this, you also need to remove the space between username= and 'hagemaru' as bash will interpret username= 'hagemaru' as running the command username= with a parameter of 'hagemaru' which is not valid as there is no username= command in bash.

echo "Enter Username"
read name
username='hagemaru'
if [ $name == $username ]
  then
    echo "Valid Username"
else
    echo "Entered Username is invalid"
    exit 1
fi
exit 0
