Use https://github.com/NightMachinary/prefixer instead. I'll continue to support bugfixes for rmprefix, as it's a very lightweight command and I still use it in my scripts, but prefixer is better in virtually every way.
cargo install --git https://github.com/NightMachinary/rmprefix --force
rmprefix removes the given prefix from its input if present. The input is split using the given separator, by default newlines.
Usage: rmprefix <prefix> [<input-separator>=\n] [<output-separator>=\n]
Set the separators to \x00 for the NUL character.
rmprefix can also work as a search and replace tool, with this neat trick:
rmprefix '' SEARCH_FOR_ME REPLACE_WITH_ME

echo "Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago." | rmprefix '' butter cheese
