substitute a string within an array?

[sicario]

Hello,

I have found a couple of ways of replacing text within an array, but can't get either of them to work. This would point to human error, but I can't see where I'm going wrong:

(1)

@config = map {s/oldtext/newtext/g; $_; } @config;

for $t (0 .. $#config)
{
print"$config[$t][0]\n";
}

This doesn't produce the expected results though, as the oldtext remains and has not been changed at all.

(2)
The 2nd approach I have tried is:

for (@config) {s/oldtext/newtext/g}

and when I print this out using the same bit of code as above, this doesn't work either.


So can somebody please tell me how I can replace text within an array (each element is a line of text)???

thanks!
