Subject: [PATCH] Remove redundant echo statement for mod

In this Bash script, mod is declared using local inside the check_even function, which means it is accessible only within that function. Therefore, mod prints correctly inside the function but does not exist outside it. As a result, the final echo $mod prints nothing. Bash does not throw an error for undefined variables; it simply expands them to an empty string.
