Do you only need the last line or are you processing each line of the file?
If you only need the last line you can use:
while (READIN) {
$last = $_;
}
# ... perform your match on $last here

could you not also do
open(FILE, file_for_read.txt);
@array = FILE;
$last_line_number = $#array;
$last_line = $array[$last_line_number];
??
you may have to add one or subtract one I can't remember =)

You could do that but if the file is VERY large it can take up quie a bit of
memory to hold the whole file in the array.

Another possibility is to begin by
appending a known unique new last line, testing for it each time, and quitting
when you reach it.

Hi
I use while (my $line = READIN) {...} to read a file, how can I determine
if a line is the last line in the file since I
Hello.
I am accustomed to trapping errors and piping them to Unix Mail.
Does anyone know of a utility to be exploited this way under DOS?
Thanks in advance,

There are several Perl SMTP modules that will work with both
Windows/DOS and Unix. That would be my first preference. Check the CPAN
archive http://www.perl.com/CPAN-local/.
Or, you can use blat which most sites seem to prefer
