Linux默认文件权限

Question

Is there someway to set the default file permission in Linux? That is, the file permission for a newly created file (regardless of the context for which it was created ). I know about putting umask in the shell startup but that only works for shell sessions. When I transfer files to a Linux box using pscp , the file is always created with permissions of 664 (rw-rw-r--). The has occurred across every flavor of Linux that I've used. This is especially annoying when I pscp a file to shared Linux machine (like my ISP). Until I can shell in and chmod the permission, the file is basically sitting there with read access for everyone, which is not exactly secure.

Answer 1

Put the umask in the non-interactive shell startup ( .bash_profile , .zshenv , .tcshrc depending on your shell). Then it'll run for non-login sessions.

Answer 2

如果要影响整个系统，还可以将其放在/ etc / profile中
