tail [OPTION]... [FILE]...

-c, --bytes=K
output the last K bytes; alternatively, use -c +K to output
bytes starting with the Kth of each file

-f, --follow[={name|descriptor}]
output appended data as the file grows; -f, --follow, and --fol‐
low=descriptor are equivalent

-F same as --follow=name --retry

-n, --lines=K
output the last K lines, instead of the last 10; or use -n +K to
output lines starting with the Kth

--max-unchanged-stats=N
with --follow=name, 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). With
inotify, this option is rarely useful.

--pid=PID
with -f, terminate after process ID, PID dies

-q, --quiet, --silent
never output headers giving file names

--retry
keep trying to open a file even when it is or becomes inaccessi‐
ble; useful when following by name, i.e., with --follow=name

-s, --sleep-interval=N
with -f, sleep for approximately N seconds (default 1.0) between
iterations. With inotify and --pid=P, check process P at least
once every N seconds.

-v, --verbose
always output headers giving file names

--help display this help and exit

--version
output version information and exit

If the first character of K (the number of bytes or lines) is a '+',
print beginning with the Kth item from the start of each file, other‐
wise, print the last K items in the file. K may have a multiplier suf‐
fix: b 512, kB 1000, K 1024, MB 1000*1000, M 1024*1024, GB
1000*1000*1000, G 1024*1024*1024, and so on for T, P, E, Z, Y.
