UMASK(1)        DOMAIN/IX Reference Manual (SYS5)        UMASK(1)



NAME
     umask - set file-creation mode mask

USAGE
     umask [ ooo ]

DESCRIPTION
     Umask sets your file-creation mode mask to ooo.  The three
     octal digits refer to read/write/execute permissions for
     owner, group, and others, respectively.  The value of each
     specified digit is subtracted from the corresponding
     ``digit'' specified by the system for the creation of a
     file.  Refer to creat (2) for more information about file
     creation.  Also see chmod (1) and umask (2) for further dis-
     cussion of file permissions.

     If ooo is omitted, the current value of the mask is printed.

     Umask is recognized and executed by the Shell.

EXAMPLE
     To remove write permission of the group and others, execute
     the following command.  Files normally created with mode 777
     become mode 755; files created with mode 666 become mode
     644.
