Recording and replaying terminal sessions in Linux can be done in a variety of ways, the following tools and methods are commonly used.

The Script command is a simple terminal session logger that can record terminal sessions and save them in a file to start recording sessions:

script -a mysession.txt

The -a option appends output to a file instead of overwriting it.

You can press Ctrl-D to end the recording session. To view session records, run the cat or less command:

cat mysession.txt

tmux and screen are two powerful terminal multiplexers that allow users to access the same session from multiple terminals and record the session. tmux logs a session to start a new tmux session:

Tmux

To start recording a session:

tmux start-server

tmux new -s mysession

tmux pipe-pane 'cat >> mysession.txt'

To stop recording a session:

tmux pipe-pane

To open a new screen session, record the session with screen:

screen -S mysession

Start recording:

:logfile mysession.txt

:log on

Stop recording:

:log off

asciinema can be used as an alternative to the script command to record terminal sessions, asciinema can record sessions and generate a shareable video of terminal sessions. Installation:

sudo apt-get install asciinema  # Debian/Ubuntu

sudo yum install asciinema      # CentOS/RHEL

Records:

asciinema rec mysession.cast

Play:

asciinema play mysession.cast

View and share sessions:

Upload the.cast file to asciinema.org, generating a web link that anyone can use to view your session online.

Make sure you don't disclose sensitive information such as passwords, API keys, etc., when logging a session.

The recorded session files can be large, especially long sessions, so clean up old session records regularly.

When using tmux and screen, make sure you are familiar with their commands and shortcuts to manage your session more effectively.

With these tools and methods, you can easily record and replay Linux terminal sessions. To automatically save terminal session records, run the following command:

script -a session.log

This command saves all output from the current session to the session.log file. To end the session log, press Ctrl-D.

You can also create a script to automatically log sessions, and create a script save_session.sh to start a new script session and save it to a time-stamped file.

#! /bin/bash

# Get the current date and time

timestamp=$(date +"%Y-%m-%d_%H-%M-%S")

# Start a new script session and save it to a time-stamped file

script -a session_${timestamp}.log

Give script execution permission:

chmod +x save_session.sh

You can also periodically execute the save_session.sh script by setting the cron scheduled task. Open the current user cron table:

crontab -e

Add a cron task, such as saving session logs every half hour:

*/30 * * * * /path/to/save_session.sh

*/30 * * * * is executed every 30 minutes, and /path/to/save_session.sh is the script path.

If you need more sophisticated session management, such as keeping records periodically in an ongoing session, tmux or screen may be more suitable. You can set up a tmux session and use tmux's clock-mode function to periodically save logs.

Note that you should make sure that script commands are available on your system. If not, you may need to install the bsdmainutils package. When using cron, make sure that your script path is correct and that the script has execution permissions. Check log files regularly to make sure they are created and saved correctly. With disk space in mind, clean or archive old log files regularly.

In this way, you can set up an automated system to periodically save your terminal session records.
