Check if string variable is a subset of another string variable

UNIX for Beginners Q & A

Below is my ksh shell script where I need to check if variable fileprops is a subset of $1 argument.

       echo "FILE PROPERTY: $fileprops"
        echo "PARAMETER3: $1"

        if [ "$1" == *"$fileprops"*  ]; then
           echo "We are Good. $line FILE is found to be INTACT !! "
        else
           echo "Problem on Target Server !! The file $line WAS TAMPERED. Exiting..." 
           exit 1;
        fi

I was expecting the condition to pass but it fails. See output below where fileprops is actually a subset of $1.

FILE PROPERTY:

 -rwxrwxrwx user1 2019-08-31 17:36 /fin/app/01/scripts/filename6.src 4294967295

PARAMETER1:

10.7.44.37\\n-rwxrwxrwx user1 2019-08-31 17:36 /fin/app/01/scripts/filename6.src 4294967295\\n-rw-rw-r-- user1 2019-08-30 17:31 /fin/app/01/sql/33211.sql 4294967295\\n10.7.44.34\\n-rwxrwxrwx user1 2019-08-31 17:36 /fin/app/01/scripts/filename6.src 4294967295\\n-rw-rw-r-- user1 2019-08-30 17:31 /fin/app/01/sql/33211.sql 4294967295

Output:

Problem on Target Server !! The file /fin/app/01/scripts/filename6.src WAS TAMPERED. Exiting...

Note: parameter1 is passed in single quotes and this is required.

Can you please suggest
