ssuuddoorreeppllaayy - replay sudo session logs
SSYYNNOOPPSSIISS
ssuuddoorreeppllaayy [--hhnnRRSS] [--dd _d_i_r] [--ff _f_i_l_t_e_r] [--mm _n_u_m] [--ss _n_u_m] ID
ssuuddoorreeppllaayy [--hh] [--dd _d_i_r] --ll [search expression]
DDEESSCCRRIIPPTTIIOONN
ssuuddoorreeppllaayy plays back or lists the output logs created by ssuuddoo. When
replaying, ssuuddoorreeppllaayy 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 _I_D should either be a six character sequence of digits and upper case
letters, e.g., 0100A5, or a pattern matching the _i_o_l_o_g___f_i_l_e option in the
_s_u_d_o_e_r_s file. When a command is run via ssuuddoo with _l_o_g___o_u_t_p_u_t enabled in
the _s_u_d_o_e_r_s file, a TSID=ID string is logged via syslog or to the ssuuddoo
log file. The _I_D may also be determined using ssuuddoorreeppllaayy's list mode.
In list mode, ssuuddoorreeppllaayy 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 input and output are connected to a
terminal and the --nn option is not specified, ssuuddoorreeppllaayy will operate
interactively. In interactive mode, ssuuddoorreeppllaayy 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:
`\n' or `\r' Skip to the next replay event; useful for long pauses.
` ' (space) Pause output; press any key to resume.
`<' Reduce the playback speed by one half.
`>' Double the playback speed.
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.
The options are as follows:
--dd _d_i_r, ----ddiirreeccttoorryy=_d_i_r
Store session logs in _d_i_r instead of the default,
_/_v_a_r_/_l_o_g_/_s_u_d_o_-_i_o.
--ff _f_i_l_t_e_r, ----ffiilltteerr=_f_i_l_t_e_r
Select which I/O type(s) to display. By default, ssuuddoorreeppllaayy
will display the command's standard output, standard error
and tty output. The _f_i_l_t_e_r argument is a comma-separated
list, consisting of one or more of following: _s_t_d_i_n, _s_t_d_o_u_t,
_s_t_d_e_r_r, _t_t_y_i_n, and _t_t_y_o_u_t.
--hh, ----hheellpp Display a short help message to the standard output and exit.
--ll, ----lliisstt [_s_e_a_r_c_h _e_x_p_r_e_s_s_i_o_n]
Enable "list mode". In this mode, ssuuddoorreeppllaayy will list
available sessions in a format similar to the ssuuddoo log file
format, sorted by file name (or sequence number). If a
_s_e_a_r_c_h _e_x_p_r_e_s_s_i_o_n is specified, it will be used to restrict
the IDs that are displayed. An expression is composed of the
following predicates:
command _p_a_t_t_e_r_n
Evaluates to true if the command run matches the
POSIX extended regular expression _p_a_t_t_e_r_n.
cwd _d_i_r_e_c_t_o_r_y
Evaluates to true if the command was run with the
specified current working directory.
fromdate _d_a_t_e
Evaluates to true if the command was run on or after
_d_a_t_e. See _D_a_t_e _a_n_d _t_i_m_e _f_o_r_m_a_t for a description of
supported date and time formats.
group _r_u_n_a_s___g_r_o_u_p
Evaluates to true if the command was run with the
specified _r_u_n_a_s___g_r_o_u_p. Note that unless a
_r_u_n_a_s___g_r_o_u_p was explicitly specified when ssuuddoo was
run this field will be empty in the log.
runas _r_u_n_a_s___u_s_e_r
Evaluates to true if the command was run as the
specified _r_u_n_a_s___u_s_e_r. Note that ssuuddoo runs commands
as user _r_o_o_t by default.
todate _d_a_t_e
Evaluates to true if the command was run on or prior
to _d_a_t_e. See _D_a_t_e _a_n_d _t_i_m_e _f_o_r_m_a_t for a description
of supported date and time formats.
tty _t_t_y _n_a_m_e
Evaluates to true if the command was run on the
specified terminal device. The _t_t_y _n_a_m_e should be
specified without the _/_d_e_v_/ prefix, e.g., _t_t_y_0_1
instead of _/_d_e_v_/_t_t_y_0_1.
user _u_s_e_r _n_a_m_e
Evaluates to true if the ID matches a command run by
_u_s_e_r _n_a_m_e.
Predicates may be abbreviated to the shortest unique string.
Predicates may be combined using _a_n_d, _o_r and _! operators as
well as `(' and `)' grouping (note that parentheses must
generally be escaped from the shell). The _a_n_d operator is
optional, adjacent predicates have an implied _a_n_d unless
separated by an _o_r.
--mm, ----mmaaxx--wwaaiitt _m_a_x___w_a_i_t
Specify an upper bound on how long to wait between key
presses or output data. By default, ssuuddoorreeppllaayy will
accurately reproduce the delays between key presses or
program output. However, this can be tedious when the
session includes long pauses. When the --mm option is
specified, ssuuddoorreeppllaayy will limit these pauses to at most
_m_a_x___w_a_i_t seconds. The value may be specified as a floating
point number, e.g., _2_._5. A _m_a_x___w_a_i_t of zero or less will
eliminate the pauses entirely.
--nn, ----nnoonn--iinntteerraaccttiivvee
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.
--RR, ----nnoo--rreessiizzee
Do not attempt to re-size the terminal to match the terminal
size of the session.
--SS, ----ssuussppeenndd--wwaaiitt
Wait while the command was suspended. By default, ssuuddoorreeppllaayy
will ignore the time interval between when the command was
suspended and when it was resumed. If the --SS option is
specified, ssuuddoorreeppllaayy will wait instead.
--ss, ----ssppeeeedd _s_p_e_e_d___f_a_c_t_o_r
This option causes ssuuddoorreeppllaayy 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
_s_p_e_e_d___f_a_c_t_o_r of _2 would make the output twice as fast whereas
a _s_p_e_e_d___f_a_c_t_o_r of _._5 would make the output twice as slow.
--VV, ----vveerrssiioonn
Print the ssuuddoorreeppllaayy versions version number and exit.
DDaattee aanndd ttiimmee ffoorrmmaatt
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.
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 Friday in the next (upcoming) week. Not
to be confused with "this Friday" which would match the Friday of
the current week.
last week
The current time but 7 days ago. This is equivalent to "a week
ago".
a fortnight ago
The current time but 14 days ago.
10:01 am 9/17/2009
10:01 am, September 17, 2009.
10:01 am
10:01 am on the current day.
10 10:00 am on the current day.
9/17/2009
00:00 am, September 17, 2009.
10:01 am Sep 17, 2009
10:01 am, September 17, 2009.
Note that relative time specifications do not always work as expected.
For example, the "next" qualifier is intended to be used in conjunction
with a day such as "next Monday". When used with units of weeks, months,
years, etc the result will be one more than expected. For example, "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
ssuuddoorreeppllaayy.
