昨天在mcs上拉下一个我的git 库
在设置git hook时遇到一个问题，
明明已经给了hook文件所有的权限了，但仍然显示无权操作

hint: The '.git/hooks/prepare-commit-msg' hook was ignored because it's not set as executable.
hint: You can disable this warning with `git config advice.ignoredHook false`.
文件是从windows远程连接上复制过来的，权限没问题
但仍然提示hint: The '.git/hooks/prepare-commit-msg' hook was ignored because it's not set as executable.
注意到文件名后有一个@符号，
查了一下资料，表示文件有其他元数据，应该是因为如此，导致git hook脚本执行失败了
所以查了一下去掉元数据的方式
#查询元数据
xattr -l pre-commit
#或
ls -l@ pre-commit
#删除元数据
xattr -d com.apple.quarantine pre-commit
应该是从远程桌面连接到widnows复制过来的文件被mac os标记为隔离了，用xattr -d 元数据 文件 删除这个标记就好了
