-w gives us the warnings about the possible interpretation errors in the script.

–t is used for switching on taint checking. It checks the origin of the variables where outside variables are not allowed in subshell executions and system calls.

Strict calls the strict pragma and is used to check on the usage of variables, references. It is also used to force a check on the definition.
