Unix Permissions Calculator (chmod)
Calculate Unix file permissions visually. Check read, write and execute for owner, group and others to get the octal code (e.g. 755) and symbolic notation (e.g. rwxr-xr-x).
| Entidade | Leitura (r) | Escrita (w) | Execução (x) | Octal |
|---|---|---|---|---|
| Owner Dono do arquivo | 0 | |||
| Group Grupo do arquivo | 0 | |||
| Others Outros usuários | 0 |
Presets comuns:
Código octal
000
chmod 000 arquivo

Como funciona
As permissões Unix são representadas em octal. Cada entidade (owner, group, others) tem 3 bits:
r (leitura = 4), w (escrita = 2) e x (execução = 1).
A soma dos bits ativos forma o dígito octal. Por exemplo, rwx = 4+2+1 = 7,
rw- = 4+2 = 6, r-x = 4+1 = 5.
