wtail hogs the CPU A: This is fixed since version 0.1.4. Problems watching long files Q: When watching a long file, wtail takes forever to catch up. Why does it take so long when tail does it instantly ? A: wtail counts lines, tail doesn't. I plan to mitigate--if not solve--the problem by decoupling screen output from file input. In the meantime, you might want to try Folkert's patches : http://www.vanheusden.com/Linux/ How do I watch the output of a filter ? Q: I'm running p0rnd, a demon that downloads p0rn from the net for me but its log contains IP addresses so I like to run it through p0rncook, a filter that resolves IP addresses. A: wtail in itself does not support running the files it watches through filters but your system does. If your shell is bash, try running : wtail <(p0rncook /var/log/p0rnd.log) Otherwise, try something along these lines : mkfifo ~/fifo p0rncook /var/log/p0rnd.log >~/fifo wtail ~/fifo Be aware that FIFOs and pipes don't always work transparently. Read the man page for flush(3) and look SIGPIPE up in signal(7). How do I watch files containing ANSI colour escape sequences ? Q: When I watch a file that contains escape sequences (ANSI colour escapes and the like), I get gibberish instead of colour. Are you going to add support for colour ? A: Maybe, maybe not.
