标 题: strange behavior about chmod 777 -R
发信站: BBS 未名空间站 (Mon Sep 26 14:47:54 2011, 美东)
I asked my colleague to change all files/folders under a folder to
accessible by all.
I asked her to do chmod 777 -R AAAA/
she said she did,
but i found one folder AAAA/bbb/ccc still not changed, while all files under
that folder has been changed to "777' mode. Why is that?
because she lied ?
Thanks. |

For 8 TB, chargeback will be $2,400 per month.

发帖数: 722 | 20 Unbearable lightness 是好书、好电影，这都没的说，可我觉得是不是好的爱情电影
就难说了，我觉得托马士基本没有爱情，只有情欲。或许和特瑞莎之间有一点，但基本
是特瑞莎单方面的倾注激情，本质还是个Crush。托马士和萨比娜之间呢，两个人都太
精明清醒；和其他女人都是逢场作戏。萨比娜呢，对另外那个男的始乱终弃，并不是因
为曾经托马士而除却巫山不羡云，所以和托马士倒真是一路人，却象是两只永远不能贴
近的刺猬。更不消说贴心了。
托马士最后落魄潦倒，没机会再花心了，才不得不收心从良，跟定特瑞莎过小日子。可
这时候又出车祸死了，其实这时候托马士的独特早已经消失了，活不如死。而且，不死的话说不定又出点别的事儿。
米兰昆德拉是伟大的，但是绝对是因为灰暗而伟大。米兰昆德拉让我想起张爱玲，而托马士让我想起胡兰成。
也许我看书太片面了。 |

这k个数应该越接近越好吧，
所以我感觉是不是只用考虑相邻的k个数？
请统计牛人出面解答一下?
