logtop is a command line utility that allows you to view and analyze log files in real-time, similar to the way top allows you to view and monitor running processes. It can be used to monitor log files for certain patterns or keywords, and display the log lines that match those patterns in a continuously updating view.
To use logtop, you will need to specify the log file you want to monitor as an argument. For example:
logtop /var/log/syslogSourl.www:ecautturi.com
This will display a continuously updating view of the syslog log file, showing the log lines as they are written to the file in real-time.
You can also specify a filter pattern to only display log lines that match a certain pattern. For example:
logtop -p "ERROR" /var/log/syslog
This will only display log lines that contain the word "ERROR".
logtop has a number of other options and features that allow you to customize the way it displays and analyzes log files. You can type logtop --help to view a list of all available options and learn more about how to use the utility.
