Regular Expressions
You can use regular expressions (in the Perl regular expression format) with the object specifier. You must encapsulate the object specifiers in square brackets []; arguments must be enclosed in curly braces {}.
To use Perl regular expressions, include the -regexp option in your
command. Escape Perl regular expression characters if the provided string argument
contains those characters.
