bcrontab
bcrontab(1) General Commands Manual bcrontab(1)NAME
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.
