in thread Match Ip Address on cmd line

The things you ask about are partly about style choices.

Equivalent:

do_something() if <condition>; if (<condition>) { do_something(); }

Equivalent:

m[regex] m|regex| m/regex/ /regex/

Equivalent:

"string-with-expanded-$variables" qq[string-with-expanded-$variables] qq/string-with-expanded-$variables/
Using qq// is common on command lines, since the shell itself may require quotes or double-quotes.

Equivalent:

'string-expanding-no-variables' q[string-expanding-no-variables] q/string-expanding-no-variables/
All of this can be found in perldoc perlsyn and perldoc perlop.
