用过bsd或unix系统的友人,是否见过这个符号
用过bsd或unix系统的朋友,是否见过这个符号
我的系统是mac OSX,在权限列表处发现了个奇怪的符号。
这里没法发图,我就贴文本吧。
drwxr-xr-x+ 48 angryfrog staff 1632 11 20 10:49 .
drwxr-xr-x 6 root admin 204 10 10 14:54 ..
-rw------- 1 angryfrog staff 5 2 10 2012 .CFUserTextEncoding
-rw-r--r--@ 1 angryfrog staff 24580 11 17 03:51 .DS_Store
drwx------ 2 angryfrog staff 68 11 20 10:49 .Trash
-rw------- 1 angryfrog staff 0 10 11 15:32 .Xauthority
drwxr-xr-x 4 angryfrog staff 136 2 11 2012 .adobe
-rw------- 1 angryfrog staff 8706 11 20 03:05 .bash_history
请看第四行,-rw-r--r--@,最后有个"@",这个符号我在centos上没有找到过。其他的linux我估计也没有。
由于mac OS内核darwin是基于freebsd核openbsd的,所以想请教下是否有人知道这个符号的含义。我在cu的bsd版提问没有得到答案。在csdn的unix区也提问了。但都没得到答案。我现在甚至有点怀疑这是darwin特有的符号了。
孤陋寡闻了,如果您知道,请告知其含义,我也琢磨了好久,但实在看不出到底是什么含义。
------最佳解决方案--------------------
昨天查了好久也没查到这个原因,看了下自己的mac以及linux服务器,也没有发现这个符号,原来是额外的东西啊,学习了,非常感谢楼主把答案公布。
------其他解决方案--------------------
在unix版问到答案了。这个属性表示此文件或此目录含有额外属性。比如在mac上下载文件后双击打开,会提示诸如“此文件来自网络下载不安全”之类的,这种标识就来自这个额外属性中,可以用xattr -l命令查看。
额外属性并不是mac的独有,只不过ls -al后,[email protected]
从mac上打包文件copy到linux上,这个属性会导致linux上打开失败,就是这个属性作怪。所以从mac上打包时需要tar -x去掉这个属性到linux。
先不结贴,就当给大家也提个醒吧
