Thank you! However, I'm not sure it's worthwhile to write such a program in C when it can be done so concisely e.g., with Perl (for N=100): > -M, --max-length=<n> remove lines longer than <n> perl -ne 'my $x = $_; chomp; length > 100 or print $x' perl -ne 'my $x = $_; chomp; print $x if length <= 100' > -m, --min-length=<n> remove lines shorter than <n> perl -ne 'my $x = $_; chomp; length < 100 or print $x' perl -ne 'my $x = $_; chomp; print $x if length >= 100' I readily admit that we can't expect everyone to use Perl, but for simple things like this, adding a few examples to the manual might be appropriate. However, there must already be good collections of useful Perl one-liners, so maybe a pointer to such a collection would be better. _______________________________________________ Bug-coreutils mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-coreutils
