Replace

[The Hobo]

How would I go about making a Replace function in CGI/Perl?

If I wanted to replace all the j's in a variable with p's, how could I do it?

Use Regular Expressions, one of the greating things in Perl and imitated by many other languages.

So I would do something like:

$string = "The dog is a flick rat-tat-tat."
$string =~ tr/a/ae/;

To get "The dog is ae flick raet-taet-taet" ??

(This isn't the exact thing I'm doing, just an example)

[JoshT]

$string = "The dog is a flick rat-tat-tat.";
$string =~ s/a/ae/; 
print "$string\n";

tr is another function, not a RegExp.

Alright, that works, but when I try to do something like this:

$string = "My Name is Bill (William)";
$string =~ s/(/ ( /; 
print "$string\n";

But it craps out on me?

( and ) have special meaning - escape them like this:

$string =~ s/\(/ \( /;

ah, I should have known that.

Thanks for all this help, Josh! It would have taken me forever to figure all this out on my own. Thanks again.
