SUDOREPLAY(8) MAINTENANCE COMMANDS SUDOREPLAY(8)
NAME
sudoreplay - replay sudo session logs
SYNOPSIS
sudoreplay [-d directory] [-f filter] [-m max_wait] [-s speed_factor] ID
sudoreplay [-d directory] -l [search expression]
DESCRIPTION
sudoreplay plays back or lists the session 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 be
a six character sequence of digits and upper case letters, e.g. 0100A5, which is logged by sudo when a command is run
with session logging enabled.
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.
-l 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.

Exactly one day from now.
yesterday
24 hours ago.
2 hours ago

next Friday
