tail: Output the last part of files
tail prints the last part (10 lines by default) of each
file; it reads from standard input if no files are given or
when given a file of `-'. Synopses:
tail [option]... [file]... tail -number [option]... [file]... tail +number [option]... [file]...
If more than one file is specified,
tail prints a
one-line header consisting of
==> file name <==
before the output for each file.
tail can output any amount of data (some other versions of
tail cannot). It also has no `-r' option (print in
reverse), since reversing a file is really a different job from printing
the end of a file; BSD
tail (which is the one with
only reverse files that are at most as large as its buffer, which is
typically 32k. A more reliable and versatile way to reverse files is
tail accepts two option formats: the new one, in which numbers
are arguments to the options (`-n 1'), and the old one, in which
the number precedes any option letters (`-1' or `+1').
If any option-argument is a number n starting with a `+',
tail begins printing with the nth item from the start of
each file, instead of from the end.
The program accepts the following options. Also see section Common options.
-c, or `l' to mean count by lines, or other option letters (`cfqv').
tailprints a header whenever it gets output from a different file, to indicate which file that output is from.
