Code:

INOTAIL(1)						       Inotify enhanced tail							INOTAIL(1)

NAME
inotail - A fast and lightweight version of tail using inotify SYNOPSIS
inotail [OPTION]... [FILE]... DESCRIPTION
inotail is a replacement for the 'tail' program found in the base installation of every Linux/UNIX system. It makes use of the inotify in- frastructure in recent versions of the Linux kernel to speed up tailing files in the follow mode (the '-f' option). Standard tail polls the file every second by default while inotail listens to special events sent by the kernel through the inotify API to determine whether a file needs to be reread. Note: inotail will not work on systems running a kernel without inotify. To enable inotify, please set CONFIG_INOTIFY=y in your Linux kernel configuration and recompile it. Currently inotail is not fully compatible to neither POSIX or GNU tail but might be in the future. OPTIONS
-c N, --bytes=N output the last N bytes. If the first character of N is a '+', begin printing with the Nth character from the start of each file. -f, --follow keep the file(s) open and print appended data as the file grows -n N, --lines=N output the last N lines (default: 10) If the first character of N is a '+', begin printing with the Nth line from the start of each file. -v, --verbose print headers with file names -h, --help show help and exit -V, --version show inotail version and exit AUTHOR
