Linux - "umask 220" in .bash_bashprofile
i'm about to install an oracle client 11g on my RedHat and SLES Linux distribution. However, the documentation says, that i have to set "umask 220" in users profile ".bash_bashprofile" . I know that this settings just subtract bit by bit the user rights. But how does this function generelly? If this setting is set in .bash_bashprofile? What does it mean generelly for the
concernning user? Does he have an overall right of 447 for all his directories? I would be pleased, if anyone could explain me that.
