!!NAME


tail - output the last part of files
!!SYNOPSIS


__tail__ [[''OPTION'']... [[''FILE'']...
!!DESCRIPTION


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.


__--retry__


keep trying to open a file even if it is inaccessible when
tail starts or if it becomes inaccessible later __--__
useful only with __-f__


__-c__, __--bytes__=''N''


output the last N bytes


__-f__, __--follow[[=__{name|descriptor}]


output appended data as the file grows; __-f__,
__--follow__, and __--follow__=''descriptor'' are
equivalent


__-n__, __--lines__=''N''


output the last N lines, instead of the last 10


__--max-unchanged-stats__=''N''


see the texinfo documentation (the default is
5)


__--max-consecutive-size-changes__=''N''


see the texinfo documentation (the default is
200)


__--pid__=''PID''


with __-f__, terminate after process ID, PID
dies


__-q__, __--quiet__, __--silent__


never output headers giving file names


__-s__, __--sleep-interval__=''S''


with __-f__, sleep S seconds between
iterations


__-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 N (the number of bytes or lines)
is a `+', print beginning with the Nth item from the start
of each file, otherwise, print the last N items in the file.
N may have a multiplier suffix: b for 512, k for 1024, m for
1048576 (1 Meg). A first OPTION of __-VALUE__ or +VALUE
is treated like __-n__ VALUE or __-n__ +VALUE unless
VALUE has one of the [[bkm] suffix multipliers, in which case
it is treated like __-c__ VALUE or __-c__
+VALUE.


With __--follow__ (-f), tail defaults to following the
file descriptor, which means that even if a tail'ed file is
renamed, tail will continue to track its end. This default
behavior is not desirable when you really want to track the
actual name of the file, not the file descriptor (e.g., log
rotation). Use __--follow__=''name'' in that case.
That causes tail to track the named file by reopening it
periodically to see if it has been removed and recreated by
some other program.
