View Linux Log Files: Complete Guide

To view the log files of a Linux system, you can use the following command:

1. View the content of a log file using the cat command, for example: cat /var/log/messages.
2. Use the less or more command to view the contents of a log file page by page, for example: less /var/log/messages.
3. Check the last few lines of a log file using the ‘tail’ command, for example: tail /var/log/messages.
4. Use the grep command to search for specific content in log files, for example: grep “error” /var/log/messages.
5. Check system logs using the journalctl command, for example: journalctl.
