Related to file and directory permissions and umask: Why the command umask (shows the octal form) and umask -S (shows the symbolic form) show different (actually the option -S shows the bits negations of the octal form)? I was expecting the umask in symbolic form for umask 024 to be u=---,g=w,o=r but it shows like this:
[user1@server-base ~]$ umask
0024
[user1@server-base ~]$ umask -S
u=rwx,g=rx,o=wx
