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 NUM bytes; or use -c +NUM to output starting
with byte NUM of each file
output appended data as the file grows;
an absent option argument means 'descriptor'
-F same as --follow=name --retry
output the last NUM lines, instead of the last 10; or use -n
+NUM to output starting with line NUM
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 if it is inaccessible
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
line delimiter is NUL, not newline
--help display this help and exit
tor (e.g., log rotation). Use --follow=name in that case. That causes
tail to track the named file in a way that accommodates renaming,
removal and creation.
