LINUX的7777是指什么??





最上面那个有什么用??


------解决方案--------------------
改权限呀,777 应该是最高权限,拥有所有操作权限。
------解决方案--------------------
Readable =4 Writable=2 Executable=1
7=4+2+1 也就是拥有所有权限
777 的三位分别代表 owner、group、other三种用户
------解决方案--------------------
首先,你的图片中只有 777,而不是你说的 7777
777分别代表 owner、group、other,即文件主、用户组、其他用户
的 读、写、执行 权限
------解决方案--------------------
root 权限...想干嘛干嘛
