目录权限'S'是什么意思?(不是小写,而是大写)
我下载了Eclipse,解压后做了一些其他的事情,然后突然发现了这个有趣的行为:
^_^ ~/Downloads > sudo chmod 0000 eclipse/
^_^ ~/Downloads > stat eclipse/
File: 'eclipse/'
Size: 4096 Blocks: 8 IO Block: 4096 directory
Device: 801h/2049d Inode: 529725 Links: 9
Access: (2000/d-----S---) Uid: ( 0/ root) Gid: ( 0/ root)

‘S'权限对一个目录意味着什么?为什么它不让我把它删除?
谢谢。
