If you mean the -M operator inside Perl code see:

http://perldoc.perl.org/functions/-X.html

(Accessible as "perldoc -f -X" - "-f" for function.).

If you mean the command-line flag, see:

http://perldoc.perl.org/perlrun.html

("perldoc perlrun").

Hope it helps.

Hi Feng,

> What's the meaning of Perl's "-M" operator?

`-M` is a command switch. It is used to load a module and is equivalent to
`use`-ing a module within the script. `-M` is different from `-m` in that the
former executes `import` function of the module whereas the latter does not
import any function except for the ones that have been explicitly listed with
the command switch.

Command switches are documented in `perlrun`.
