14 | .SH DESCRIPTION |
| 15 | .I Tail | |
| 16 | copies the named file to the standard output beginning | |
| 17 | at a designated place. | |
| 18 | If no file is named, the standard input is used. | |
| 19 | .PP | |
| 20 | Copying begins at distance | |
| 21 | .I +number | |
| 22 | from the beginning, or | |
| 23 | .I \-number | |
| 24 | from the end of the input. | |
| 25 | .I Number | |
| 26 | is counted in units of lines, blocks or characters, | |
| 27 | according to the appended option | |
| 28 | .B l, | |
| 29 | .B b | |
| 30 | or | |
| 31 | .B c. | |
| 32 | When no units are specified, counting is by lines. | |
| 33 | .PP | |
| 34 | Specifying | |
| 35 | .B r | |
| 36 | causes tail to print lines from the end of the file in reverse order. | |
| 37 | The default for | |
| 38 | .B r | |
| 39 | is to print the entire file this way. | |
| 40 | Specifying | |
| 41 | .B f | |
| 42 | causes | |
| 43 | .I tail | |
| 44 | to not quit at end of file, but rather wait and try to read repeatedly | |
| 45 | in hopes that the file will grow. | |

| 48 | .SH BUGS | |
| 49 | Tails relative to the end of the file | |
| 50 | are treasured up in a buffer, and thus | |
| 51 | are limited in length. | |
| 52 | .PP | |
| 53 | Various kinds of anomalous behavior may happen | |
| 54 | with character special files. |
