tail - Print the last 10 lines of each FILE to standard output.
With more than one FILE, precede each with a header giving the file name.
With no FILE, or when FILE is -, read standard input.
Mandatory arguments to long flags are mandatory for short flags
too.

- -c, --bytes
- Number of bytes to print
- -f, --follow
- Print the file as it grows
[possible values: descriptor, name]
- -n, --lines
- Number of lines to print
- --pid=PID
- With -f, terminate after process ID, PID dies
- -q, --quiet
- Never output headers giving file names
- -s,
--sleep-interval=N
- Number of seconds to sleep between polling the file when running with
-f
- --max-unchanged-stats=N
- Reopen a FILE which has not changed size after N (default 5) iterations to
see if it has been unlinked or renamed (this is the usual case of rotated
log files); This option is meaningful only when polling (i.e., with
--use-polling) and when --follow=name
- -v, --verbose
- Always output headers giving file names
- -z,
--zero-terminated
- Line delimiter is NUL, not newline
- --use-polling
- Disable 'inotify' support and use polling instead
- --retry
- Keep trying to open a file if it is inaccessible
- -F
- Same as --follow=name --retry
- -h, --help
- Print help
- -V, --version
- Print version
- [files]
