.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBsudoreplay\fR [\fB\-h\fR] [\fB\-d\fR \fIdirectory\fR] [\fB\-f\fR \fIfilter\fR] [\fB\-m\fR \fImax_wait\fR] [\fB\-s\fR \fIspeed_factor\fR] \s-1ID\s0
.PP
\&\fBsudoreplay\fR [\fB\-h\fR] [\fB\-d\fR \fIdirectory\fR] \-l [search expression]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBsudoreplay\fR plays back or lists the output logs created by \fBsudo\fR.
When replaying, \fBsudoreplay\fR 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 \fI\s-1ID\s0\fR should either be a six character sequence of digits and
upper case letters, e.g. \f(CW\*(C`0100A5\*(C'\fR, or a pattern matching the
\&\fIiolog_file\fR option in the \fIsudoers\fR file.  When a command is run
via \fBsudo\fR with \fIlog_output\fR enabled in the \fIsudoers\fR file, a
\&\f(CW\*(C`TSID=ID\*(C'\fR string is logged via syslog or to the \fBsudo\fR log file.
The \fI\s-1ID\s0\fR may also be determined using \fBsudoreplay\fR's list mode.
.PP
In list mode, \fBsudoreplay\fR can be used to find the \s-1ID\s0 of a session
based on a number of criteria such as the user, tty or command run.
.PP
In replay mode, if the standard output has not been redirected,
\&\fBsudoreplay\fR will act on the following keys:
.IP "' ' (space)" 8
.IX Item "' ' (space)"
Pause output; press any key to resume.
.IP "'<'" 8
Reduce the playback speed by one half.
.IP "'>'" 8
Double the playback speed.
.SH "OPTIONS"
.IX Header "OPTIONS"
\&\fBsudoreplay\fR accepts the following command line options:
.IP "\-d \fIdirectory\fR" 12
.IX Item "-d directory"
Use \fIdirectory\fR to for the session logs instead of the default,
\&\fI/var/log/sudo\-io\fR.
.IP "\-f \fIfilter\fR" 12
.IX Item "-f filter"
By default, \fBsudoreplay\fR will play back the command's standard
output, standard error and tty output.  The \fI\-f\fR option can be
used to select which of these to output.  The \fIfilter\fR argument
is a comma-separated list, consisting of one or more of following:
\&\fIstdout\fR, \fIstderr\fR, and \fIttyout\fR.
.IP "\-h" 12
.IX Item "-h"
The \fB\-h\fR (\fIhelp\fR) option causes \fBsudoreplay\fR to print a short
help message to the standard output and exit.
.IP "\-l [\fIsearch expression\fR]" 12
.IX Item "-l [search expression]"
Enable \*(L"list mode\*(R".  In this mode, \fBsudoreplay\fR will list available
sessions in a format similar to the \fBsudo\fR log file format, sorted
by file name (or sequence number).  If a \fIsearch expression\fR is
specified, it will be used to restrict the IDs that are displayed.
An expression is composed of the following predicates:
.RS 12
.IP "command \fIcommand pattern\fR" 8
.IX Item "command command pattern"
Evaluates to true if the command run matches \fIcommand pattern\fR.
On systems with \s-1POSIX\s0 regular expression support, the pattern may
be an extended regular expression.  On systems without \s-1POSIX\s0 regular
expression support, a simple substring match is performed instead.
.IP "cwd \fIdirectory\fR" 8
.IX Item "cwd directory"
Evaluates to true if the command was run with the specified current
working directory.
.IP "fromdate \fIdate\fR" 8
.IX Item "fromdate date"
Evaluates to true if the command was run on or after \fIdate\fR.
See \*(L"Date and time format\*(R" for a description of supported
date and time formats.
.IP "group \fIrunas_group\fR" 8
.IX Item "group runas_group"
Evaluates to true if the command was run with the specified
\&\fIrunas_group\fR.  Note that unless a \fIrunas_group\fR was explicitly
specified when \fBsudo\fR was run this field will be empty in the log.
.IP "runas \fIrunas_user\fR" 8
.IX Item "runas runas_user"
Evaluates to true if the command was run as the specified \fIrunas_user\fR.
Note that \fBsudo\fR runs commands as user \fIroot\fR by default.
.IP "todate \fIdate\fR" 8
.IX Item "todate date"
Evaluates to true if the command was run on or prior to \fIdate\fR.
See \*(L"Date and time format\*(R" for a description of supported
date and time formats.
.IP "tty \fItty\fR" 8
.IX Item "tty tty"
Evaluates to true if the command was run on the specified terminal
device.  The \fItty\fR should be specified without the \fI/dev/\fR prefix,
e.g.  \fItty01\fR instead of \fI/dev/tty01\fR.
.IP "user \fIuser name\fR" 8
.IX Item "user user name"
Evaluates to true if the \s-1ID\s0 matches a command run by \fIuser name\fR.
.RE
.RS 12
.Sp
Predicates may be abbreviated to the shortest unique string (currently
all predicates may be shortened to a single character).
.Sp
Predicates may be combined using \fIand\fR, \fIor\fR and \fI!\fR operators
as well as \f(CW\*(Aq(\*(Aq\fR and \f(CW\*(Aq)\*(Aq\fR for grouping (note that parentheses
must generally be escaped from the shell).  The \fIand\fR operator is
optional, adjacent predicates have an implied \fIand\fR unless separated
by an \fIor\fR.
.RE
.IP "\-m \fImax_wait\fR" 12
.IX Item "-m max_wait"
Specify an upper bound on how long to wait between key presses or
output data.  By default, \fBsudo_replay\fR will accurately reproduce
the delays between key presses or program output.  However, this
can be tedious when the session includes long pauses.  When the
\&\fI\-m\fR option is specified, \fBsudoreplay\fR will limit these pauses
to at most \fImax_wait\fR seconds.  The value may be specified as a
floating point number, .e.g. \fI2.5\fR.
.IP "\-s \fIspeed_factor\fR" 12
.IX Item "-s speed_factor"
This option causes \fBsudoreplay\fR 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
\&\fIspeed_factor\fR of \fI2\fR would make the output twice as fast whereas
a \fIspeed_factor\fR of <.5> would make the output twice as slow.
.IP "\-V" 12
.IX Item "-V"
The \fB\-V\fR (version) option causes \fBsudoreplay\fR to print its version number
and exit.
.SS "Date and time format"
.IX Subsection "Date and time format"
The time and date may be specified multiple ways, common formats include:
.IP "\s-1HH:MM:SS\s0 am \s-1MM/DD/CCYY\s0 timezone" 8
.IX Item "HH:MM:SS am MM/DD/CCYY timezone"
24 hour time may be used in place of am/pm.
.IP "\s-1HH:MM:SS\s0 am Month, Day Year timezone" 8
.IX Item "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.
.IP "CCYY-MM-DD \s-1HH:MM:SS\s0" 8
.IX Item "CCYY-MM-DD HH:MM:SS"
\&\s-1ISO\s0 time format
.IP "\s-1DD\s0 Month \s-1CCYY\s0 \s-1HH:MM:SS\s0" 8
.IX Item "DD Month CCYY HH:MM:SS"
The month name may be abbreviated.
.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.  For example, the following
are all valid:
.PP
The following are all valid time and date specifications:
.IP "now" 8
.IX Item "now"
