Its
umask and not
unmask. You can find more documentation on it by refering to the bash_builtins via the umask manpages. Try
man umask on your console. Its a good doc, very yummy. I'd recommend reading it entirely. For what its worth, here's the scoop from ~ line 1450 or so.
umask [-p] [-S] [mode]
The user file-creation mask is set to mode. If
mode begins with a digit, it is interpreted as an
octal number; otherwise it is interpreted as a sym
bolic mode mask similar to that accepted by
chmod(1). If mode is omitted, or if the -S option
is supplied, the current value of the mask is
printed. The -S option causes the mask to be
printed in symbolic form; the default output is an
octal number. If the -p option is supplied, and
mode is omitted, the output is in a form that may
be reused as input. The return status is 0 if the
mode was successfully changed or if no mode argu
ment was supplied, and false otherwise.
HTH!
