Summary

When comparing the command output with a string,
shell_exec() can returns false or null.

If it returns null, trim will receives NULL value,
and that's behavior is deprecated under PHP 7.4+:

trim(null) would return:

Deprecated: trim(): Passing null to parameter #1 ($string)
of type string is deprecated
