bcron-update(8)             System Manager's Manual            bcron-update(8)



NAME
       bcron-update - Update system crontabs.

SYNOPSIS
       bcron-update path [ path ...  ]

DESCRIPTION
       bcron-update polls the named files or directories periodically to see
       if there are any new, changed, or removed files.  When it detects
       changes, it mirrors those changes into the crontab spool directory.
       bcron-update runs as root in order to be able to read system files that
       would potentially be unreadable otherwise.

       On Debian, if path is a directory, bcron-update skips files in this
       directory with names that do not solely consist of lower- and uppercase
       letters ('a'-'z', 'A'-'Z'), digits ('0'-'9'), underscores ('_'), and
       hyphens ('-').

EXAMPLES
       To mirror modern vixie-cron's behavior, use:
       bcron-update /etc/crontab /etc/cron.d

ENVIRONMENT
       BCRON_SPOOL
            The spool directory for bcron.  Defaults to /var/spool/cron.

       BCRON_USER
            After writing files and before moving them into their final
            location, bcron-update changes the ownership of the file to this
            user so that bcron-sched can read them.

SEE ALSO
       bcron-sched(8)

DIAGNOSTICS
       bcron-update outputs three different kinds of messages about actions it
       is taking.

       Rescanning /etc/cron.d
            The named directory has been modified, and will be scanned to
            determine what files have been added or deleted.

       -/etc/cron.d/oldfile
            The named file no longer exists and will be removed from the
            spool.

       +/etc/cron.d/newfile
            The named file was either created or modified since the last scan,
            and will be copied into the spool.
