LogWatcher

LogWatcher is an utility meant as a replacement for: tail -F /some/path/*.

lw vs tail advantages:

• it watches for modified, deleted and new files without restart of the utility
• it won't crash if there are > 4096 files (shell pattern limit exhaustion) or directories (if you set ulimit -n value high enough)
• it works recursively on directories
