NAME

       sudoreplay - replay sudo session logs

SYNOPSIS

       sudoreplay [-h] [-d directory] [-f filter] [-m max_wait] [-s
       speed_factor] ID

       sudoreplay [-h] [-d directory] -l [search expression]

DESCRIPTION

       sudoreplay plays back or lists the output logs created by sudo.  When
       replaying, sudoreplay can play the session back in real-time, or the
       playback speed may be adjusted (faster or slower) based on the command
       line options.

       The ID should either be a six character sequence of digits and upper
       case letters, e.g. 0100A5, or a pattern matching the iolog_file option
       in the sudoers file.  When a command is run via sudo with log_output
       enabled in the sudoers file, a TSID=ID string is logged via syslog or
       to the sudo log file.  The ID may also be determined using sudoreplay's
       list mode.

       In list mode, sudoreplay can be used to find the ID of a session based
       on a number of criteria such as the user, tty or command run.

       In replay mode, if the standard output has not been redirected,
       sudoreplay will act on the following keys:

       ' ' (space)
               Pause output; press any key to resume.

       '<'     Reduce the playback speed by one half.

       '>'     Double the playback speed.

OPTIONS

       sudoreplay accepts the following command line options:

       -d directory
                   Use directory to for the session logs instead of the
                   default, /var/log/sudo-io.

       -f filter   By default, sudoreplay will play back the command's
                   standard output, standard error and tty output.  The -f
                   option can be used to select which of these to output.  The
                   filter argument is a comma-separated list, consisting of
                   one or more of following: stdout, stderr, and ttyout.

       -h          The -h (help) option causes sudoreplay to print a short
                   help message to the standard output and exit.

       -l [search expression]
                   Enable "list mode".  In this mode, sudoreplay will list
                   available session IDs.  If a search expression is
                   specified, it will be used to restrict the IDs that are
                   displayed.  An expression is composed of the following
                   predicates:

                   command command pattern
                           Evaluates to true if the command run matches
                           command pattern.  On systems with POSIX regular
                           expression support, the pattern may be an extended
                           regular expression.  On systems without POSIX
                           regular expression support, a simple substring
                           match is performed instead.

                   cwd directory
                           Evaluates to true if the command was run with the
                           specified current working directory.

                   fromdate date
                           Evaluates to true if the command was run on or
                           after date.  See "Date and time format" for a
                           description of supported date and time formats.

                   group runas_group
                           Evaluates to true if the command was run with the
                           specified runas_group.  Note that unless a
                           runas_group was explicitly specified when sudo was
                           run this field will be empty in the log.

                   runas runas_user
                           Evaluates to true if the command was run as the
                           specified runas_user.  Note that sudo runs commands
                           as user root by default.

                   todate date
                           Evaluates to true if the command was run on or
                           prior to date.  See "Date and time format" for a
                           description of supported date and time formats.

                   tty tty Evaluates to true if the command was run on the
                           specified terminal device.  The tty should be
                           specified without the /dev/ prefix, e.g.  tty01
                           instead of /dev/tty01.

                   user user name
                           Evaluates to true if the ID matches a command run
                           by user name.

                   Predicates may be abbreviated to the shortest unique string
                   (currently all predicates may be shortened to a single
                   character).

                   Predicates may be combined using and, or and ! operators as
                   well as '(' and ')' for grouping (note that parentheses
                   must generally be escaped from the shell).  The and
                   operator is optional, adjacent predicates have an implied
                   and unless separated by an or.

       -m max_wait Specify an upper bound on how long to wait between key
                   presses or output data.  By default, sudo_replay will
                   accurately reproduce the delays between key presses or
                   program output.  However, this can be tedious when the
                   session includes long pauses.  When the -m option is
                   specified, sudoreplay will limit these pauses to at most
                   max_wait seconds.  The value may be specified as a floating
                   point number, .e.g. 2.5.

       -s speed_factor
                   This option causes sudoreplay to adjust the number of
                   seconds it will wait between key presses or program output.
                   This can be used to slow down or speed up the display.  For
                   example, a speed_factor of 2 would make the output twice as
                   fast whereas a speed_factor of <.5> would make the output
                   twice as slow.

       -V          The -V (version) option causes sudoreplay to print its
                   version number and exit.

   Date and time format
       The time and date may be specified multiple ways, common formats
       include:

       HH:MM:SS am MM/DD/CCYY timezone
               24 hour time may be used in place of am/pm.

       HH:MM:SS am Month, Day Year timezone
               24 hour time may be used in place of am/pm, and month and day
               names may be abbreviated.  Note that month and day of the week
               names must be specified in English.

       CCYY-MM-DD HH:MM:SS
               ISO time format

       DD Month CCYY HH:MM:SS
               The month name may be abbreviated.

       Either time or date may be omitted, the am/pm and timezone are
       optional.  If no date is specified, the current day is assumed; if no
       time is specified, the first second of the specified date is used.  The
       less significant parts of both time and date may also be omitted, in
       which case zero is assumed.  For example, the following are all valid:

       The following are all valid time and date specifications:

       now     The current time and date.

       tomorrow
               Exactly one day from now.

       yesterday
               24 hours ago.

       2 hours ago
               2 hours ago.

       next Friday
               The first second of the next Friday.

               The current time but the first day of the coming week.
