Restricting users from certain directories

You can release disk space and possibly keep it free by restricting access to directories and monitoring disk usage.

  1. Restrict users from certain directories by typing:
    chmod 755 DirName
    This command sets read and write permissions for the owner (root) and sets read-only permissions for the group and others. DirName is the full path name of the directory you want to restrict.
  2. Monitor the disk usage of individual users by adding the following line to the /var/spool/cron/crontabs/adm file:
    0 2 * * 4 /usr/sbin/acct/dodisk
    This line runs the dodisk command at 2 a.m. (0 2) each Thursday (4). The dodisk command initiates disk-usage accounting. This command is usually run as part of an accounting procedure that is run by the cron command during off-peak hours.
