看命令帮助时,看到ls 中的文件的权限字符有:
t;T;s;S看不太懂解释
s the set-user-ID or set-group-ID bit is on, and the
corresponding user or group execution bit is also on
S undefined bit-state (the set-user-ID bit is on and the
user execution bit is off)
t the 1000 (octal) bit, or sticky bit, is on (see
chmod(1)), and execution is on
T the 1000 bit is turned on, and execution is off
l mandatory locking occurs during access (the set-
group-ID bit is on and the group execution bit is off)
L mandatory locking occurs during access (the set-
group-ID bit is on and the group execution bit is off)
有高手能解释一下吗??
这些字符究竟是作什么用的?? |
