How to view Tomcat log files on Linux?

To view Tomcat log files, you can follow these steps:

1. Open the terminal or command line interface.
2. Navigate to the “logs” folder in the Tomcat installation directory. By default, Tomcat log files are located in the “logs” folder within the Tomcat installation directory. You can use the cd command to enter this directory. For example: cd /opt/tomcat/logs.
3. Use the command ls or dir to view the list of files in this directory. Tomcat log files typically have prefixes such as catalina, localhost, manager, and host-manager, and end with the .log extension. For example: ls
4. View the content of the log file using the cat command. For example: cat catalina.out.
5. If you want to view the real-time updates of log files, you can use the tail command. For example: tail -f catalina.out. This will display the new log content in real-time.
6. You can use the grep command to filter the contents of a log file. For example, “cat catalina.out | grep ‘error'” can filter out log lines that contain “error”.

Please note that the above commands are to be run in a Linux system. If you are using a Windows system, you can use similar commands such as using dir command instead of ls command, using type command instead of cat command, etc.
