It's very convenient to monitor logs using less command - you see what is going with your system as it happening. The bad thing is that my logs are optimized for grep tool: each atomic action is always printed in a single line (I can easily lookup for actions performed by certain user then).Still, actions contain incoming messages, which are more user-friendly if being printed multiline. If I want to filter log offline, it's easy:cat ./log/system.log | tail -50 | tr '\\n' '\n'Can I do those replacements online? What I mean is that replacements are done as new text being appended to log and shown to the screen like less + G.
