Like a tail operation for viewing live updates -e or –page-end Show all characters, even long and unprintable lines and characters -f or –follow You can think of running journalctl -f as doing a tail operation on the system log. The –follow flag is used for the tail operation. You can use the journalctl command to print all the system logs, you can query it with a finer grained query, and sometimes you just want to TAIL the system logs to watch the system live as it operates. The data is structured and indexed so its not like you are searching plain text files using grep, you have much more advanced searching and finding capabilities. Journalctl is a fancy new service in linux distributions, such as Ubuntu, Debian, CentOS and others, that wraps and abstracts the system log into a command line interface tool making it easier to find what you are looking for.
