How to view and manage log files in Linux?

In a Linux system, you can view and manage log files using the following methods:

1. Viewing log files using command line tools:

1. View the contents of a log file using the cat command, for example: cat /var/log/syslog
2. To view large log files in pages, you can use the “less” or “more” command. For example: “less /var/log/syslog”
3. View the latest content of a log file in real time using the tail command, for example: tail -f /var/log/syslog.

1. Utilize a log viewing tool:

1. Check the kernel log using the dmesg command.
2. Use the journalctl command to view system logs, for example: journalctl -xe to view the last few lines of the system logs.

1. Manage log files:

1. Delete unnecessary log files using the rm command, for example: rm /var/log/syslog.1.
2. Regularly rotate and manage log files using the logrotate tool by configuring the /etc/logrotate.conf file to set rotation rules.

In general, viewing and managing log files in a Linux system typically requires using command line tools and specific tools to handle different types of log files.
