30 | normally copies out all the text currently in the file | |
31 | before beginning to watch for new text. | |
32 | The option | |
33 | .B \- | |
34 | alone causes only new material to be given. | |
35 | .PP | |

37 | is particularly useful for alternately watching the output | |
38 | file being written by a long shell script or a long-running | |
39 | program and doing real work. | |
