Emacs - como corrigir um arquivo - Eshell não suporta redirecionamento de entrada

Question

Ao tentar executar um patch a partir de um buffer de Eshell (por exemplo, patch nsfns.m < nsfns.diff ), recebo uma mensagem de erro (abaixo). Existe uma maneira de aplicar um patch usando um buffer Eshell? Se não, existe outro modo principal de emulação de tipo de terminal que permitirá a aplicação de um patch?

Você pode contornar isso com cat nsfns.diff | patch nsfns.m .
