plays back or lists the output logs created by When replaying, 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 should either be a six character sequence of digits and upper case letters, e.g., or a path name. The may include an optional suffix which may be used to start replaying at a specific time offset. The is specified as a number in seconds since the start of the session with an optional decimal fraction.
Path names may be relative to the I/O log directory
(unless overridden by the option) or fully qualified, beginning with a character. When a command is run via with enabled in the file, a string is logged via syslog or to the log file. The may also be determined using list mode.
In list mode, 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 option is not specified, will operate interactively. In interactive mode, 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: Skip to the next replay event; useful for long pauses. 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: Store session logs in instead of the default,
Select which I/O type(s) to display. By default, will display the command's standard output, standard error, and tty output. The argument is a comma-separated list, consisting of one or more of following: and Enable When replaying a session, will ignore end-of-file and keep replaying until the log is complete. This can be used to replay a session that is still in progress, similar to An I/O log file is considered to be complete when the write bits have been cleared on the session's timing file. Versions of prior to 1.9.1 do not clear the write bits upon completion. Display a short help message to the standard output and exit. Enable In this mode, will list available sessions in a format similar to the log file format, sorted by file name (or sequence number). Any control characters present in the log data are formatted in octal with a leading character. For example, a horizontal tab is displayed as and an embedded carriage return is displayed as Space characters in the command name and arguments are also formatted in octal.
If a is specified, it will be used to restrict the IDs that are displayed. An expression is composed of the following predicates: Evaluates to true if the command run matches the POSIX extended regular expression Evaluates to true if the command was run with the specified current working directory. Evaluates to true if the command was run on or after See for a description of supported date and time formats. Evaluates to true if the command was run with the specified Unless a was explicitly specified when was run this field will be empty in the log. Evaluates to true if the command was run on the specified Evaluates to true if the command was run as the specified By default, runs commands as the user. Evaluates to true if the command was run on or prior to See for a description of supported date and time formats. Evaluates to true if the command was run on the specified terminal device. The should be specified without the
prefix, e.g.,
instead of
Evaluates to true if the ID matches a command run by
Predicates may be abbreviated to the shortest unique string.
Predicates may be combined using and operators as well as and grouping (parentheses must generally be escaped from the shell). The operator is optional, adjacent predicates have an implied unless separated by an Specify an upper bound on how long to wait between key presses or output data. By default, will accurately reproduce the delays between key presses or program output. However, this can be tedious when the session includes long pauses. When the option is specified, will limit these pauses to at most seconds. The value may be specified as a floating point number, e.g., A of zero or less will eliminate the pauses entirely. 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. Do not attempt to re-size the terminal to match the terminal size of the session. Wait while the command was suspended. By default, will ignore the time interval between when the command was suspended and when it was resumed. If the option is specified, will wait instead. This option causes 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 of would make the output twice as fast whereas a of would make the output twice as slow. Print the versions version number and exit. The time and date may be specified multiple ways, common formats include: 24 hour time may be used in place of am/pm. 24 hour time may be used in place of am/pm, and month and day names may be abbreviated. Month and day of the week names must be specified in English. ISO time format 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: The current time and date. Exactly one day from now. 24 hours ago. 2 hours ago. The first second of the Friday in the next (upcoming) week. Not to be confused with which would match the Friday of the current week. The current time but 7 days ago. This is equivalent to The current time but 14 days ago. 10:01 am, September 17, 2009. 10:01 am on the current day. 10:00 am on the current day. 00:00 am, September 17, 2009. 10:01 am, September 17, 2009.
Relative time specifications do not always work as expected. For example, the qualifier is intended to be used in conjunction with a day such as When used with units of weeks, months, years, etc the result will be one more than expected. For example, 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 versions 1.8.4 and higher support a flexible debugging framework that is configured via lines in the file.
