journalctl:tldr:56e95

The command "journalctl -f" is used to continuously follow the system journal in real-time. Here is a breakdown of its components:

• "journalctl" is a command-line utility used to view, query, and manipulate the systemd journal, which is a centralized log that stores various system activity and event logs.
• "-f" is a short form of "--follow", which instructs journalctl to continuously display newly appended messages as they are written to the journal. It "follows" the journal in real-time, similar to the "tail -f" command used for regular log files.

By running "journalctl -f" in the terminal, you can monitor the live output of the system journal, seeing the recent log entries continuously as they are added. This can be helpful for real-time troubleshooting, monitoring system activity, or observing events as they occur.
