推荐答案

数字的权限是3个八进制数字.例如，当转换为3个二进制数时，555为101 101 101，它对应于r-x r-x r-x.第一组是所有者，第二组是组，第三组是其他人.

Permissions as numbers are 3 octal numbers. 555, for example, when converted to 3 binary numbers is 101 101 101 which would correspond to r-x r-x r-x. The first set is owner, second set is group, third set is everyone else.

r =已读

w =写

x =执行

如果缺少任何这些(-)，则该集合没有这些权限.

If any of those are missing (-), then that set does not have those permissions.
