PerlIO::via::EscStatus::ShowNone - suppress all status lines
use PerlIO::via::EscStatus::ShowNone; binmode (STDOUT, ':via(EscStatus::ShowNone)') or die;
EscStatus::ShowNone is a variant of the EscStatus layer which doesn't show any status lines coming through the stream at all, only the ordinary output. This can be used for a batch mode or non-interactive mode in a program.
Of course for batch mode it's also possible simply not to print statuses in the first place. You can decide whether it's easier to check a mode flag at the print, or push a layer to strip what's printed. A layer may be easier for suppressing prints from a library or independent parts of a program.
See examples/shownone.pl in the PerlIO-via-EscStatus sources for a complete program using ShowNone.
