Imagine being able to use tail to follow multiple files in one window. That is what MultiTail does. MultiTail is a Linux administrators’ dream come true. With the ability to follow any log file (and as many log files as you can stand in one window) MultiTail can stack multiple tails of log files vertically or horizontally, with colors or without.
Commands like multitail -s 2 /var/log/messages /var/log/security.log will follow the messages and the security.log logs in two vertical columns in one window. MultiTail is very easy to use.
