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.
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 descrip‐
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.
