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.

bcrontab - Manage users crontab files
SYNOPSIS
bcrontab [ -u user ] file
bcrontab [ -u user ] { -l | -r | -e }
DESCRIPTION
bcrontab interfaces with the bcron-spool daemon to manage crontab files in the privileged spool directory.
OPTIONS -u user
Tell bcron-spool that we are acting on behalf of the named user. bcron-spool will only accept the username if bcrontab is running
as either root or the same user ID as the named user.
-l List the cronab crontab to standard output.
-r Remove the user's crontab.
-e Edit the current crontab.
ENVIRONMENT
VISUAL If this is set, it is used as the editor to invoke to edit a crontab.
EDITOR If $VISUAL is not set and this is, it is used as the editor to invoke to edit a crontab. If neither are set, /bin/vi is used.
BCRON_SOCKET
The path to the named socket used to communicate with bcron-spool. Defaults to /var/run/bcron-spool.
LOGNAME
USER These two variables are used, in order, to determine the user name invoking the program. One must be set if the -u option is not
used.
FILES
bcrontab tries to writes a temporary file into the current directory, and then into /tmp if that fails, in order to edit the current
crontab.
