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.

EXIT STATUS

       aptitude-robot-session  exits  with  0 on success, 1 if dpkg is locked, 2 if apt failed to fetch some APT
       repositories.

BUGS

       The  non-interactive  nature  of  aptitude-robot-session  may   trigger   the   condition   reported   in
       https://bugs.launchpad.net/ubuntu/+source/aptitude/+bug/257279
