Quais são os códigos de erro padrão no Linux?

Quando escrevo um código no bash, por exemplo, que copia um arquivo, quando o arquivo não existe, no terminal, vejo um erro semelhante a "arquivo não encontrado", se o usuário do script não receber a permissão, o erro mostrado up é semelhante a "permissão negada".

Basicamente, qualquer que seja a linguagem de programação, quando você escreve um código para copiar um arquivo, por exemplo, a linguagem de programação que você está usando solicitará ao SO (linux no meu caso) que faça isso, se algo errado acontecer, o SO responderá com o erro conveniente (código + mensagem).

Existe um comando que eu possa executar que listará todos os códigos de erro padrão no sistema?

O errnocomando pode fazer isso. De man errno:

DESCRIPTION
       errno looks up errno macro names, errno codes, and the corresponding descriptions. For example, if given ENOENT on a Linux system, it prints
       out the code 2 and the description "No such file or directory".  If given the code 2, it prints ENOENT and the same description.

OPTIONS
       -l, --list
              List all errno values.

Então, para ver todos eles, execute:

$ errno -ls
