使用 UMASK 创建具有 755 权限的 unix 文件

Question

I want to create unix file with permission of 755. if I use umask of 022, the file gets created with 644. Why is that? Why files are not getting created with execute permission? What's the way around?

Answer 1

The x permission is not applied by default to files. It is applied to directories, and compliation programs like "make" will apply it to executable files. Beyond that, for the most part, the x permission must be applied manually.
