inotail (1) - Linux Man Pages
inotail: A fast and lightweight version of tail using inotify
inotail - A fast and lightweight version of tail using inotify
is a replacement for the 'tail' program found in the base installation of every
Linux/UNIX system. It makes use of the inotify infrastructure 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.
- -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
