2 | Each 'w' command typed so far has written the edited material | |
3 | back on the same file that it came from originally. | |

5 | w camden | |
6 | will write the current editor buffer | |
7 | on file 'camden'. What does the following | |
8 | sequence of commands do? | |
9 | ed old | |
10 | w new | |
11 | q | |
12 | As you can see, it picks up file 'old', and | |
13 | writes it on file 'new'. It has the same effect | |
14 | as | |
15 | cp old new | |
16 | does. | |
17 | ||
18 | In this directory there is a file named "old". | |
19 | Copy that file to file "new" with the editor, using | |
20 | the commands given above. Check by printing | |
21 | both files with "cat" that they are the same. | |
22 | Type "ready" when done. | |
