.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
aptitude-robot-session
.SH "DESCRIPTION"
.IX Header "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 (\s-1STDERR\s0 and \s-1STDOUT\s0) to \s-1LOGFILE\s0 defined in \f(CW\*(C`/etc/default/aptitude\-robot\*(C'\fR.
.SH "CONFIGURATION"
.IX Header "CONFIGURATION"
There are a few configuration options that can be defined in \f(CW\*(C`/etc/default/aptitude\-robot\*(C'\fR.
.IP "\s-1LOGFILE\s0" 4
.IX Item "LOGFILE"
the name of the file where all the output of aptitude-robot is collected.
Defaults to \f(CW\*(C`/var/log/aptitude\-robot.log\*(C'\fR
.IP "\s-1LOG_SESSION\s0" 4
.IX Item "LOG_SESSION"
the name of the file where the session log is accumulated.
aptitude-robot-session will append its \s-1PID\s0 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
\&\s-1LOGFILE\s0 and delete the session log.
.IP "\s-1SESSION_REPORT_COMMAND\s0" 4
.IX Item "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.
.IP "\s-1MAX_LOGFILES_SIZE_BLOCKS\s0" 4
.IX Item "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.
.Sp
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.
.IP "\s-1POST_SESSION_HOOK\s0" 4
.IX Item "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.
.SH "BUGS"
.IX Header "BUGS"
The non-interactive nature of aptitude-robot-session may trigger the condition
reported in https://bugs.launchpad.net/ubuntu/+source/aptitude/+bug/257279
