Re: Re: dos EOF in linux

well, the problem is that the dos eof appears on its own line, so when im processing the lines, heres what happens:

...
open INPUT_HANDLE ....
    or die ...

while ( my $line = <INPUT_HANDLE> ) {
    chomp $line;
    last if my_eof_test($line, \*INPUT_HANDLE);
    process_line($line);
}
close(INPUT_HANDLE);
...
[download]

i feel that i need this test because otherwise, the line that contains just the EOF will read properly, because there it is data, even though its the DOS EOF. because the read is true, we get in the while loop, and the line containing just EOF gets sent to process_line(). am i missing something here?

As far as I know this isnt an issue. But im a win32 user. :-) And may I point out that `while ( my $line = <INPUT_HANDLE>) {` [download] is not the same as (excepting the variable used) `while ( <INPUT_HANDLE> ) {` [download] I believe that should read `while ( defined ( my $line= <INPUT_HANDLE> ) ) {` [download] But personally I dont see the point. You shouldnt be afraid of using $_. --- demerphq my friends call me, usually because I'm late....	[reply] [d/l] [select]

It shouldn't matter but if you are worried about processing the EOF marker, try this... `... open INPUT_HANDLE .... or die ... while ( my $line = <INPUT_HANDLE> ) { chomp $line; process_line($line); last if eof(INPUT_HANDLE); } close(INPUT_HANDLE); ...` [download]	[reply] [d/l]
