perl matching
# Basic syntax: $your_string =~ /regex pattern to match/ # Use !~ for not matching # Example usage: # Check if the regex pattern your is found in the variable $your_string my $your_string = "this is your string"; if ($your_string =~ /your/) { print "your_string contains your\n" } --> your_string contains your # Check if the regex pattern y?o*u+r is found in the variable $your_string my $your_string = "this is your string"; if ($your_string =~ /y?o*u+r/) { print "your_string matches pattern\n" } --> your_string matches pattern # Where, in regex: # - ? matches 0 or 1 of the preceeding characters # - * matches 0 or more of the preceeding characters # - + matches 1 or more of the preceeding characters
