I don't mean to critisize your code, especially when you haven't asked for this type of comment, but CGI.pm will handle all the parameters for you, so you don't need all the stuff on line five to fourteen. You could even change them to $log=param('username');$pass=param('password');

It will also generate all the HTML for you. Ovid has an excellent tutorial linked to on his home node that has helped me with CGI a great deal, and talks about why you shouldn't try get the parameters the way you have. He also wrote use CGI or Die;.

Actually, merlyn beat me to it.

[Cosmic37]: if ( $line =~ /$mydt/ ) { print $line; }
[Cosmic37]: I try to match successive date times stored in variable $mydt
[Cosmic37]: I guess it is searching for the string "$mydt"
[Corion]: Indeed cool, erix ;)
[Cosmic37]: rather than the value of $mydt which is a date time strong such as 2016-01-01 12:30:56
[Corion]: Cosmic37: No, but maybe $mydt doesn't contain what you think it does, or it contains characters that are special in a regular expression? Try if( $line =~ /\Q$mydt\E/) { ... for a literal match
[Cosmic37]: I mean string grrr
[Corion]: Maybe add an else branch in which you print what the values of $line and $mydt are?
[Cosmic37]: ah thank you I will try
[Cosmic37]: you are right $mydt did not contain what I expected... :-D I will now think :-D
