## 12.9. Finer Control on tail

What if you need to look at the last 11 lines of the file? The command `tail -``n` shows the final `n` lines. The command `tail +``n` discards the first `n`-1 lines, giving you line `n` and everything that follows it.

You can also tell tail to count the number of characters or the number of 512-byte blocks. To do so, use the -c option (count characters) or the -b option (count blocks). If you want to state explicitly that you're interested in lines, give the -l option.

Your tail probably has a -r option that shows the file in reverse order, starting from the last line.

Many versions of Unix limit the maximum number of lines that tail, especially tail -r, can display.
