charactor manipulation help

[ignoranceisblis]

could anyone briefly describe a couple different ways of manipulating individual charactors within a string?

i.e. determining if a string has an "s" at the end of it, and removing it, then replacing it

and iand how could I say if ($string eq "<a href="any value">) then
$string = "the site URL"

any ideas?;

You could do this: s/s$//; which would replace any string with an "s" at the end of it. (only the "s");

if ($string eq = "<a href='whatever'>") {
$string = "site url";
}

why do you want to remove the s then put it back on again?

simply check if its there and if not add it.

unless ( $string =~ m/s$/i ){
$string .= 's';
}

the first line tests to see if theres an s at the end and only goes so the second line if not. The 'i' at the end makes it ignor case. the second line just appends an s onto the end of the string with .=

if you do what to remove the s then use what Wig posted

$string =~ s/s$//;
