Could somebody please tell me what command is used in Perl to put text in lower case format. Let's say I have $text = "AbCdEfG". How can I make that value equal to "abcdefg"?

I believe you would use

$text=~ tr/[A-Z]/[a-z]/;

to translate capitals into lowercase.

Thank you for the advise. What I am trying to do is put all email addresses that my script works with into lower case. So that, for example, email address AbCd222@AoL.CoM would be changed into abcd222@aol.com. When I apply the command that you suggested to email addresses, the simbol @ ruins it all. In my example, address AbCd222@AoL.CoM would be changed into abcd222.com. Could somebody please suggest how I can make this work?

doesn't 'lc' work?

eg
lc $string;

No, I get the same result. The code below gives me "abcd222.com" instead of "abcd222@aol.com".

$text = "AbCd222@AoL.CoM";
$text = lc $text;

You can escape sequence the @ sign using the \ character.

$text = "AbCd222\@AoL.CoM";
$text = lc $text;
print $text;

will display

abcd222@aol.com

Alternatively use the ' instead of "

ie
$text = 'AbCd222@AoL.CoM';
$text = lc $text;
print $text;

will display
abcd222@aol.com

I haven't been able to try this yet because I do not have FTP on my laptop to upload this and try it, but I believe the following should work.

//The following variable is the email address (for example)
//that you would want to make all lowercase.

$str_email = "AbHdCgYeefE@aol.com";

//Below is another variable which takes in the above variable
//and should make it all lowercase.

$str_conv = strtolower($str_email);

//From this point you could echo/print the above variable if you
//wish to display it. You can use it to enter into a database
//instead of the direct user input. ect

Again, sorry if it does not work; but I am unable to test that at the moment.

As the previous poster stated.. this almost works...
Change the "s to 's

Otherwords you're interpolating the value of the AoL.CoM array.
