NAME

       aptitude-robot-session - call aptitude-robot non-interactively

SYNOPSIS

       aptitude-robot-session

DESCRIPTION

       aptitude-robot-session is a helper script meant to be run from cron or init scripts.  It will call
       aptitude-robot with some options suitable for non-interactive use.  It will also redirect all output
       (STDERR and STDOUT) to LOGFILE defined in "/etc/default/aptitude-robot".

CONFIGURATION

       There are a few configuration options that can be defined in "/etc/default/aptitude-robot".

       LOGFILE
           the name of the file where all the output of aptitude-robot is collected.  Defaults to
           "/var/log/aptitude-robot.log"

       LOG_SESSION
           the name of the file where the session log is accumulated.  aptitude-robot-session will append its
           PID to this file in order not to overwrite a log file left over from a crashed earlier invocation.
           If aptitude-robot-session finishes properly it will append the session log to LOGFILE and delete the
           session log.

       SESSION_REPORT_COMMAND
           optional command invoked with the session log as the only argument at the end of an aptitude-robot-
           session run.  This can be used to file reports to monitoring systems or support mail addresses.

       MAX_LOGFILES_SIZE_BLOCKS
           file size limit in blocks for the session log.  This prevents endless loops if a package installation
           continues to ask the same question for which no terminal is available to provide an answer.

           But be aware that this limit also affects _all_ daemons started or restarted during the aptitude-
           robot-session run, including e.g. the OpenSSH daemon which again will propagate the limit to its
           remote login sessions. Use with care.

       POST_SESSION_HOOK
           a command that is run at the end of a successful aptitude-robot-session.  E.g., use it for apt-get
           clean.
