Perl's Function



Description

This is not a function. This is the regular expression-substitution operator. Based on the regular expression specified in PATTERN, data is replaced by REPLACE. Like m//, the delimiters are defined by the first character following s.

Syntax

s/PATTERN/REPLACE/

Example

Following is the example code showing its basic usage −

#!/usr/bin/perl -w

$string = "This is Test";
# this will replace Test with Best.
$string =~ s/Test/Best/;

print "$string\n";

When above code is executed, it produces the following result −

This is Best
