+.Pp +.Nm +.Op Fl h +.Op Fl d Ar dir +.Fl l +.Op search expression +.Sh DESCRIPTION +.Nm +plays back or lists the output logs created by +.Nm sudo . +When replaying, +.Nm +can play the session back in real-time, or the playback speed may be +adjusted (faster or slower) based on the command line options. +.Pp +The +.Em ID +should either be a six character sequence of digits and +upper case letters, e.g., +.Li 0100A5 , +or a pattern matching the +.Em iolog_file +option in the +.Em sudoers +file. +When a command is run via +.Nm sudo +with +.Em log_output +enabled in the +.Em sudoers +file, a +.Li TSID=ID +string is logged via syslog or to the +.Nm sudo +log file. +The +.Em ID +may also be determined using +.Nm sudoreplay Ns 's +list mode. +.Pp +In list mode, +.Nm +can be used to find the ID of a session based on a number of criteria +such as the user, tty or command run. +.Pp +In replay mode, if the standard input and output are connected to a terminal +and the +.Fl n +option is not specified, +.Nm +will operate interactively. +In interactive mode, +.Nm +will attempt to adjust the terminal size to match that of the session and +write directly to the terminal (not all terminals support this). +Additionally, it will poll the keyboard and act on the following keys: +.Bl -tag -width 12n +.It So Li \en Sc No or So Li \er Sc +Skip to the next replay event; useful for long pauses. +.It So Li \ Sc Pq space +Pause output; press any key to resume. +.It Ql < +Reduce the playback speed by one half. +.It Ql > +Double the playback speed. +.El +.Pp +The session can be interrupted via control-C. +When the session has finished, the terminal is restored to its +original size if it was changed during playback. +.Pp +The options are as follows: +.Bl -tag -width Fl +.It Fl d Ar dir , Fl -directory Ns = Ns Ar dir +Store session logs in +.Ar dir +instead of the default, +.Pa @iolog_dir@ . +.It Fl f Ar filter , Fl -filter Ns = Ns Ar filter +Select which I/O type(s) to display. +By default, +.Nm +will display the command's standard output, standard error and tty output. +The +.Ar filter +argument is a comma-separated list, consisting of one or more of following: +.Em stdin , +.Em stdout , +.Em stderr , +.Em ttyin , +and +.Em ttyout . +.It Fl h , -help +Display a short help message to the standard output and exit. +.It Fl l , -list Op Ar search expression +Enable +.Dq list mode . +In this mode, +.Nm +will list available sessions in a format similar to the +.Nm sudo +log file format, sorted by file name (or sequence number). +If a +.Ar search expression +is specified, it will be used to restrict the IDs that are displayed. +An expression is composed of the following predicates: +.Bl -tag -width 6n +.It command Ar pattern +Evaluates to true if the command run matches the POSIX extended +regular expression +.Ar pattern . +.It cwd Ar directory +Evaluates to true if the command was run with the specified current +working directory. +.It fromdate Ar date +Evaluates to true if the command was run on or after +.Ar date . +See +.Sx Date and time format +for a description of supported date and time formats. +.It group Ar runas_group +Evaluates to true if the command was run with the specified +.Ar runas_group . +Note that unless a +.Ar runas_group +was explicitly specified when +.Nm sudo +was run this field will be empty in the log. +.It runas Ar runas_user +Evaluates to true if the command was run as the specified +.Ar runas_user . +Note that +.Nm sudo +runs commands as user +.Em root +by default. +.It todate Ar date +Evaluates to true if the command was run on or prior to +.Ar date . +See +.Sx Date and time format +for a description of supported date and time formats. +.It tty Ar tty name +Evaluates to true if the command was run on the specified terminal device. +The +.Ar tty name +should be specified without the +.Pa /dev/ +prefix, e.g., +.Pa tty01 +instead of +.Pa /dev/tty01 . +.It user Ar user name +Evaluates to true if the ID matches a command run by +.Ar user name . +.El +.Pp +Predicates may be abbreviated to the shortest unique string. +.Pp +Predicates may be combined using +.Em and , +.Em or +and +.Em \&! +operators as well as +.Ql \&( +and +.Ql \&) +grouping (note that parentheses must generally be escaped from the shell). +The +.Em and +operator is optional, adjacent predicates have an implied +.Em and +unless separated by an +.Em or . +.It Fl m , -max-wait Ar max_wait +Specify an upper bound on how long to wait between key presses or output data. +By default, +.Nm +will accurately reproduce the delays between key presses or program output. +However, this can be tedious when the session includes long pauses. +When the +.Fl m +option is specified, +.Nm +will limit these pauses to at most +.Em max_wait +seconds. +The value may be specified as a floating point number, e.g., +.Em 2.5 . +A +.Em max_wait +of zero or less will eliminate the pauses entirely. +.It Fl n , -non-interactive +Do not prompt for user input or attempt to re-size the terminal. +The session is written to the standard output, not directly to +the user's terminal. +.It Fl R , -no-resize +Do not attempt to re-size the terminal to match the terminal size +of the session. +.It Fl S , -suspend-wait +Wait while the command was suspended. +By default, +.Nm +will ignore the time interval between when the command was suspended +and when it was resumed. +If the +.Fl S +option is specified, +.Nm +will wait instead. +.It Fl s , -speed Ar speed_factor +This option causes +.Nm +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 +.Ar speed_factor +of +.Em 2 +would make the output twice as fast whereas a +.Ar speed_factor +of +.Em .5 +would make the output twice as slow. +.It Fl V , -version +Print the +.Nm +versions version number and exit. +.El +.Ss Date and time format +The time and date may be specified multiple ways, common formats include: +.Bl -tag -width 6n +.It HH:MM:SS am MM/DD/CCYY timezone +24 hour time may be used in place of am/pm. +.It 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. +.It CCYY-MM-DD HH:MM:SS +ISO time format +.It DD Month CCYY HH:MM:SS +The month name may be abbreviated. +.El +.Pp +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. +.Pp +The following are all valid time and date specifications: +.Bl -tag -width 6n +.It now +The current time and date. +.It tomorrow +Exactly one day from now. +.It yesterday +24 hours ago. +.It 2 hours ago +2 hours ago. +.It next Friday +The first second of the Friday in the next (upcoming) week. +Not to be confused with +.Dq this Friday +which would match the Friday of the current week. +.It last week +The current time but 7 days ago. +This is equivalent to +.Dq a week ago . +.It a fortnight ago +The current time but 14 days ago. +.It 10:01 am 9/17/2009 +10:01 am, September 17, 2009. +.It 10:01 am +10:01 am on the current day. +.It 10 +10:00 am on the current day. +.It 9/17/2009 +00:00 am, September 17, 2009. +.It 10:01 am Sep 17, 2009 +10:01 am, September 17, 2009. +.El +.Pp +Note that relative time specifications do not always work as expected. +For example, the +.Dq next +qualifier is intended to be used in conjunction with a day such as +.Dq next Monday . +When used with units of weeks, months, years, etc +the result will be one more than expected. +For example, +.Dq next week +will result in a time exactly two weeks from now, which is probably +not what was intended. +This will be addressed in a future version of +.Nm . +.Ss Debugging sudoreplay +.Nm +versions 1.8.4 and higher support a flexible debugging framework +that is configured via +.Li Debug +lines in the +.Xr sudo.conf @mansectform@ +file. +.Pp +For more
