20 sudoreplay - replay sudo session logs
24 B<sudoreplay> [B<-h>] [B<-d> I<directory>] [B<-f> I<filter>] [B<-m> I<max_wait>] [B<-s> I<speed_factor>] ID
26 B<sudoreplay> [B<-h>] [B<-d> I<directory>] -l [search expression]
30 B<sudoreplay> plays back or lists the session logs created by
31 B<sudo>. When replaying, B<sudoreplay> can play the session back
32 in real-time, or the playback speed may be adjusted (faster or
33 slower) based on the command line options. The I<ID> should be
34 a six character sequence of digits and upper case letters, e.g.
35 0100A5, which is logged by B<sudo> when a command is run with
36 session logging enabled.
38 In list mode, B<sudoreplay> can be used to find the ID of a session
39 based on a number of criteria such as the user, tty or command run.
41 In replay mode, if the standard output has not been redirected,
42 B<sudoreplay> will act on the following keys:
48 Pause output; press any key to resume.
52 Reduce the playback speed by one half.
56 Double the playback speed.
62 B<sudoreplay> accepts the following command line options:
68 Use I<directory> to for the session logs instead of the default,
73 By default, B<sudoreplay> will play back the command's standard
74 output, standard error and tty output. The I<-f> option can be
75 used to select which of these to output. The I<filter> argument
76 is a comma-separated list, consisting of one or more of following:
77 I<stdout>, I<stderr>, and I<ttyout>.
81 The B<-h> (I<help>) option causes B<sudoreplay> to print a short
82 help message to the standard output and exit.
84 =item -l [I<search expression>]
86 Enable "list mode". In this mode, B<sudoreplay> will list available
87 session IDs. If a I<search expression> is specified, it will be
88 used to restrict the IDs that are displayed. An expression is
89 composed of the following predicates:
93 =item command I<command pattern>
95 Evaluates to true if the command run matches I<command pattern>.
96 On systems with POSIX regular expression support, the pattern may
97 be an extended regular expression. On systems without POSIX regular
98 expression support, a simple substring match is performed instead.
100 =item cwd I<directory>
102 Evaluates to true if the command was run with the specified current
105 =item fromdate I<date>
107 Evaluates to true if the command was run on or after I<date>.
108 See L<"Date and time format"> for a description of supported
109 date and time formats.
111 =item group I<runas_group>
113 Evaluates to true if the command was run with the specified
114 I<runas_group>. Note that unless a I<runas_group> was explicitly
115 specified when B<sudo> was run this field will be empty in the log.
117 =item runas I<runas_user>
119 Evaluates to true if the command was run as the specified I<runas_user>.
120 Note that B<sudo> runs commands as user I<root> by default.
124 Evaluates to true if the command was run on or prior to I<date>.
125 See L<"Date and time format"> for a description of supported
126 date and time formats.
130 Evaluates to true if the command was run on the specified terminal
131 device. The I<tty> should be specified without the F</dev/> prefix,
132 e.g. F<tty01> instead of F</dev/tty01>.
134 =item user I<user name>
136 Evaluates to true if the ID matches a command run by I<user name>.
140 Predicates may be abbreviated to the shortest unique string (currently
141 all predicates may be shortened to a single character).
143 Predicates may be combined using I<and>, I<or> and I<!> operators
144 as well as C<'('> and C<')'> for grouping (note that parentheses
145 must generally be escaped from the shell). The I<and> operator is
146 optional, adjacent predicates have an implied I<and> unless separated
151 Specify an upper bound on how long to wait between key presses or
152 output data. By default, B<sudo_replay> will accurately reproduce
153 the delays between key presses or program output. However, this
154 can be tedious when the session includes long pauses. When the
155 I<-m> option is specified, B<sudoreplay> will limit these pauses
156 to at most I<max_wait> seconds. The value may be specified as a
157 floating point number, .e.g. I<2.5>.
159 =item -s I<speed_factor>
161 This option causes B<sudoreplay> to adjust the number of seconds
162 it will wait between key presses or program output. This can be
163 used to slow down or speed up the display. For example, a
164 I<speed_factor> of I<2> would make the output twice as fast whereas
165 a I<speed_factor> of <.5> would make the output twice as slow.
169 The B<-V> (version) option causes B<sudoreplay> to print its version number
174 =head2 Date and time format
176 The time and date may be specified multiple ways, common formats include:
180 =item HH:MM:SS am MM/DD/CCYY timezone
182 24 hour time may be used in place of am/pm.
184 =item HH:MM:SS am Month, Day Year timezone
186 24 hour time may be used in place of am/pm, and month and day names
187 may be abbreviated. Note that month and day of the week names must
188 be specified in English.
190 =item CCYY-MM-DD HH:MM:SS
194 =item DD Month CCYY HH:MM:SS
196 The month name may be abbreviated.
200 Either time or date may be omitted, the am/pm and timezone are
201 optional. If no date is specified, the current day is assumed; if
202 no time is specified, the first second of the specified date is
203 used. The less significant parts of both time and date may also
204 be omitted, in which case zero is assumed. For example, the following
207 The following are all valid time and date specifications:
213 The current time and date.
217 Exactly one day from now.
229 The first second of the next Friday.
233 The current time but the first day of the coming week.
235 =item a fortnight ago
237 The current time but 14 days ago.
239 =item 10:01 am 9/17/2009
241 10:01 am, September 17, 2009.
245 10:01 am on the current day.
249 10:00 am on the current day.

255 =item 10:01 am Sep 17, 2009
257 10:01 am, September 17, 2009.
265 =item F</var/log/sudo-io>
267 The default I/O log directory.
269 =item F</var/log/sudo-io/00/00/01/log>
271 Example session log info.
273 =item F</var/log/sudo-io/00/00/01/stdin>
