m operator in Perl is used to match a pattern within the given text. The string passed to m operator can be enclosed within any character which will be used as a delimiter to regular expressions.
To print this matched pattern and the remaining string, m operator provides various operators which include $, which contains whatever the last grouping match matched.
$& – contains the entire matched string
$` – contains everything before the matched string
$’ – contains everything after the matched string
0 on failure and 1 on success
