displaying portions of a string

[lindajames]

Hello everyone, I have the code below that is in a script i have and basically this code is used to display the customers password:

$str = "$r{'passwd'}";
if ($str eq undef) { $str = " "; }
bodyprint("<td>$str</td>");

At the moment it displays the customers full password and I want it to just display the first two characters of the password. Can anyone tell me how this can be done?

Any suggestions would be much appreciated.

Cheers
Linda

If perl, try the substr keyword ([perldoc.com ]). On the botton you may try something like:

$trunc_str = substr ($str, 0, 2);
bodyprint ("<td>$trunc_str</td>");

Just use a negative offset as explained in the substr [perldoc.com] documentation.

substr [perldoc.com] $string, -1 , 1 

will return the last character.
