Re^3: 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(); }
[download]

Equivalent:

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

Equivalent:

"string-with-expanded-$variables"
qq[string-with-expanded-$variables]
qq/string-with-expanded-$variables/
[download]

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/
[download]

All of this can be found in perldoc perlsyn and perldoc perlop.
