unlike other tools like iconv(1), a crop(1) without arguments or with ones resulting in a no-op, like `-t 0 0', errors out. other options like `-i 0' do not error. this breaks assumptions and results in tedious intermediary steps or hacks like: foo | {crop -t $1 $2 >[2]/null || cat} > baz.bit instead, just ignore the check. subsequent code doesn't make assumptions on that. |
