Linux log files location and how do I view logs files?

Almost all logfiles are located under /var/log directory (and subdirectory). You can change to this directory using cd command but you need to be the root user. You can use less, more, cat or tail command to see the logs.

Go to /var/logs directory:# cd /var/logsView common log file /var/log/messages using any one of the following command:# tail -f /var/log/messages
# less /var/log/messages
# more -f /var/log/messages
# vi /var/log/messages
