Perl to replace a string

Suppose you have multiple files in which you would like to replace “RATE” by “RISKEQ” everywhere. Is there an easy way do so? The answer is yes. In Perl, you can use regular expression to achieve the goal. Here is the sample code. Note that this sample will create backup files too.

#!/usr/bin/perl -w
use strict;
$^I = “.bak”;
while (<>)
{
s/RATE/RISKEQ/g;
print;
}
