in reply to reading files

That would be the easiest Pure-Perl way of doing it:

open(FILE,"/path/to/file.txt") or die "could not open file: $!"; my @_lines = <FILE>; # After I open the file for reading close(FILE); if ( scalar(@_lines) >= 100 ) { shift( @_lines ) for ( 0 .. (scalar(@_lines) - 100) ); # shift removes the first element of the list # but what if you had 110 lines? you have to loop # and you start the loop at 0 because if you have 100 lines # 100 - 100 = 0 and 0 .. 0 will give you one iteration # but 1 .. 0 would not loop at all # then you overwrite the file open(FILE,">/path/to/file.txt") or die "could not open file: $!"; print FILE @_lines; close FILE; }

There are no stupid questions, but there are a lot of inquisitive idiots.
