Lista de diretórios recursivos de / proc

Question

Estou tentando obter uma listagem de diretório recursivo do meu sistema de arquivos usando o comando

$ ls -alRc 

do diretório raiz.

Tudo está funcionando bem, exceto a listagem do diretório /proc , que resulta nos seguintes erros:

ls: cannot read symbolic link ./proc/186/exe: No such file or directory

Como lidar com isso?

Obrigado antecipadamente.

    

Answer 1

Você não "lida" com isso, é normal.

/proc é um sistema de arquivos virtual, assim como /dev e /sys (se presente), para apresentar informações do sistema e fornecer uma maneira semelhante a arquivo para alterar a configuração do sistema - ou seja, esses arquivos não são t realmente no seu disco rígido.

link

Todos os tipos de links e loops quebrados e erros de E / S podem ocorrer se você tentar iterar /proc como se fosse uma pasta "normal", porque ... não é.

Então, a resposta é: você não.

Se você quiser, você pode silenciar os erros redirecionando-os para /dev/null :

$ ls -alRc 2> /dev/null

Para fins de experimentação, observe como fazer um cat /dev/null depois não imprime seus erros - porque, como dissemos, /dev é um sistema de arquivos virtual e /dev/null não é um arquivo real mas ... o análogo mais próximo de um buraco negro que você encontrará em um sistema Linux:)
