FreeKB - Regular expression delimiter
Perl - Regular expression delimiter

By default, the forward slash character is used to separate fields in regular expressions in Perl.

if ($foo =~ /hello/) { print "foo contains hello"; }

 

Using the m character, you can use a different character to separate fields in a regular expression. In this example, m is used and # is set as the delimiter.

if ($foo =~ m#hello#) { print "foo contains hello"; }
