scriptreplay – Replay all actions of a terminal session

The scriptreplay command is used to replay all the actions of a terminal session that were previously recorded by the script command. It is especially useful for demonstrations, training sessions, and debugging. The command reads the timing information from the typescript file and replays the user’s actions in real-time.

Overview

The basic syntax for the scriptreplay command is as follows:

scriptreplay [options] timingfile [typescript [divisor]]

The timingfile argument specifies the name of the file that contains the timing information. The typescript argument specifies the name of the file that contains the actual terminal session. If the typescript argument is not specified, the command reads from the standard input. The divisor argument specifies a scaling factor for the timing information. If the divisor argument is not specified, the default value of 1 is used.

Here is an example of how to use the scriptreplay command:

$ scriptreplay timingfile typescript

This command replays the actions of the terminal session recorded in the typescript file using the timing information in the timingfile file.

Use cases

The scriptreplay command is useful in a variety of situations, such as:

• Demonstrations: You can record a terminal session and then replay it later to demonstrate a particular process or procedure.
• Training sessions: You can record a terminal session and then replay it during a training session to show students how to perform a particular task.
• Debugging: You can record a terminal session and then replay it to debug a problem that occurred during the session.

Troubleshooting tips

Here are some common issues you may encounter when using the scriptreplay command and how to troubleshoot them:

• Timing issues: If the replay seems to be running too fast or too slow, try adjusting the divisor argument to scale the timing information. You can also use the -S option to scale the timing information by a specified factor.
• File not found: If the command cannot find the timingfile or typescript file, make sure you are specifying the correct file names and paths. You may also need to check file permissions.
• Invalid file format: If the typescript file was not created by the script command, the scriptreplay command may not be able to replay it properly. Make sure the typescript file was created using the script command.

Notes

• The scriptreplay command requires the script command to be installed on your system.
• The scriptreplay command may not work properly if the terminal emulator used during the recording session is different from the one used during the replay session.
