/ in </head> must be escaped with \ because / is the substitute delimiter or another delimiter can be used. for example s,<head(?:.|\n|\r)+?</head>,,g.

also as regex seems to be multi line perl switch -0777 can be used to unset record separator and read the whole file, otherwise input is split bynewlines before applying regex.
