umask (abbreviated from '''''u'''ser file creation mode '''mask''''') is a ''') - as a result of the Bitwise Exclusive OR operation of the argument and the full access mode ''777''. - as a result of the Bitwise AND of the unary Complement of the argument (using Bitwise NOT ) and the full access mode ''777''. Most Unix Shell s provide an umask command which affects all child processes executed in this shell. EXAMPLES To set the mode of newly created files to ''0600'' (''-rw --'') we need 777''8'' ^ ~177''8'' = 600''8'' Thus, umask has to be run with the value ''177'': umask 177 SEE ALSO EXTERNAL LINKS |
