MultiTail

MultiTail is a command-line log monitor, allowing users to view one or more log files in separate panes within the same terminal window. One MultiTail window can be split horizontally or vertically as many times, and split screens can be dynamically swapped and closed. In each split screen, you can see a log file in a scrolling screen like the tail command shows, or can manually scroll through a log file by using arrow up/down keys. You can search for a keyword across all split screens. Multiple log files can be merged in one screen but with different colors, and content of log files can be filtered based on regular expressions. The content shown by MultiTail can be filtered and piped into one or more files, processes or a syslog server. Besides log files, MultiTail can also monitor the output of any external programs via pipe.
