前面的权限控制符中有一个@符号，它包含了文件的扩展属性。
执行命令ls [email protected],就可以看到更多相关信息，如下所示：
ls [email protected] [email protected] 11 rlanffy staff - 374 9 28 00:27 . com.apple.metadata:kMDItemWhereFroms 73 com.apple.metadata:kMDLabel_pzd6bqzzjka6orf7oyy665upy 57 com.apple.quarantine 59drwx------+ 16 rlanffy staff - 544 10 1 19:50 .. 0: group:everyone deny [email protected] 1 rlanffy staff - 12292 9 14 10:38 .DS_Store com.apple.FinderInfo [email protected] 13 rlanffy staff - 442 9 10 11:33 .git com.apple.quarantine [email protected] 3 rlanffy staff - 102 8 14 12:10 .vagrant com.apple.quarantine [email protected] 1 rlanffy staff - 163 9 24 23:48 README.md com.apple.quarantine [email protected] 1 rlanffy staff - 4904 8 12 14:17 Vagrantfile com.macromates.crc32 8 com.macromates.selectionRange 5 com.macromates.visibleIndex [email protected] 10 rlanffy staff - 340 3 6 2015 files com.apple.quarantine [email protected] 12 rlanffy staff - 408 9 14 10:54 projects com.apple.quarantine [email protected] 8 rlanffy staff - 272 9 27 14:04 scripts com.apple.quarantine 59
想要去掉这个@符号，执行下面的命令即可：
sudo xattr -d -r com.macromates.selectionRange ./*
其中－d就表示删除扩展属性的意思，-r 表示遍历文件夹中的文件，若权限控制符中有@也会去掉。右面的域名com.macromates.selectionRange为想要删除的相关信息。
