tail [OPTION]... [FILE]...
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 options are mandatory for short options
output the last K bytes; alternatively, use -c +K to output
bytes starting with the Kth of each file
output appended data as the file grows; -f, --follow, and --fol-
low=descriptor are equivalent
-F same as --follow=name --retry
output the last K lines, instead of the last 10; or use -n +K to
output lines starting with the Kth
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.
with -f, terminate after process ID, PID dies
-q, --quiet, --silent
never output headers giving file names
keep trying to open a file even when it is or becomes inaccessi-
ble; useful when following by name, i.e., with --follow=name
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.
always output headers giving file names
--help display this help and exit
output version information and exit
tail to track the named file in a way that accommodates renaming,
removal and creation.
