linux 系统在/etc/profile中设置不同用户的的umask值
55 # By default, we want umask to get set. This sets it for login shell
56 # Current threshold for system reserved uid/gids is 200
57 # You could check uidgid reservation validity in
58 # /usr/share/doc/setup-*/uidgid file
59 if [ $UID -gt 199 ] && [ "`/usr/bin/id -gn`" = "`/usr/bin/id -un`" ]; then
60 umask 002
61 else
62 umask 022
63 fi
从上面的代码中可以看出,UID大于199的用户设置了umask为002,否则为022。所以umask值对于root用户是022,对于普通用户是002
