| 2 | A particularly important editor command | |
| 3 | is 'w' (write). This writes whatever | |
| 4 | you are working on, including everything you | |
| 5 | have typed in or changed, into a file, | |
| 6 | so that you can work on it again later. | |
| 7 | If you try to quit from the editor without | |
| 8 | writing out your changes, the editor will complain | |
| 9 | (but only once -- a second 'q' will let you out). | |
| 10 | Generally it's wisest to leave the editor by typing | |
| 11 | ||
| 12 | w | |
| 13 | q | |
| 14 | ||
| 15 | rather than just 'q'. I'll put you in the editor; | |
| 16 | type those two commands to leave. Then type | |
| 17 | "ready". | |

| 28 | Note that the editor typed 27. This is the number | |
| 29 | of characters it wrote into the file. This | |
| 30 | is reassuring - it tells you the write was | |
| 31 | successful. The count of characters read | |
| 32 | is also typed, which is why you got a '27' | |
| 33 | before your responses. | |
