NAME
umask - set or get the file-creation mask
Synopsis
umask [OPTIONS] [MASK]
Description
With no argument, the current file-creation mask is printed, if an
argument is specified, it is the new file creation mask. The mask may
be specified as an octal number, in which case it is interpreted as the
rights that should be masked away, i.e. it is the inverse of the file
permissions any new files will have.
If a symbolic mask is specified, the actual file permission bits, and
not the inverse, should be specified. A symbolic mask is a comma
separated list of rights. Each right consists of three parts:
o The first part specifies to whom this set of right applies, and can
be one of u, g, o or a, where u specifies the user who owns the file,
g specifies the group owner of the file, o specific other users
rights and a specifies all three should be changed.
o The second part of a right specifies the mode, and can be one of =, +
or -, where = specifies that the rights should be set to the new
value, + specifies that the specified right should be added to those
previously specified and - specifies that the specified rights should
be removed from those previously specified.
o The third part of a right specifies what rights should be changed and
can be any combination of r, w and x, representing read, write and
execute rights.
If the first and second parts are skipped, they are assumed to be a and
=, respectively. As an example, r,u+w means all users should have read
access and the file owner should also have write access.
o -h or --help print this message
o -S or --symbolic prints the file-creation mask in symbolic form
instead of octal form. Use man chmod for more information.
o -p or --as-command prints any output in a form that may be reused as
input
The umask implementation in fish should behave identically to the one
in bash.
Example
umask 177 or umask u=rw sets the file creation mask to read and write
for the owner and no permissions at all for any other users.
