5 Vim is a very powerful editor that has many commands, too many to | |
6 explain in a tutor such as this. This tutor is designed to describe | |
7 enough of the commands that you will be able to easily use Vim as | |
8 an all-purpose editor. | |
9 | |
10 The approximate time required to complete the tutor is 25-30 minutes, | |
11 depending upon how much time is spent with experimentation. | |
12 | |
13 ATTENTION: | |
14 The commands in the lessons will modify the text. Make a copy of this | |
12499 | 15 file to practice on (if you started "vimtutor" this is already a copy). |
1624 | 16 |
17 It is important to remember that this tutor is set up to teach by | |
18 use. That means that you need to execute the commands to learn them | |
19 properly. If you only read the text, you will forget the commands! | |
20 | |
13231 | 21 Now, make sure that your Caps-Lock key is NOT depressed and press |
14347 | 22 the j key enough times to move the cursor so that lesson 1.1 |
1624 | 23 completely fills the screen. |
24 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |

26 | |
27 | |
28 ** To move the cursor, press the h,j,k,l keys as indicated. ** | |
29 ^ | |
30 k Hint: The h key is at the left and moves left. | |
31 < h l > The l key is at the right and moves right. | |
32 j The j key looks like a down arrow. | |
33 v | |
34 1. Move the cursor around the screen until you are comfortable. | |
35 | |
36 2. Hold down the down key (j) until it repeats. | |
37 Now you know how to move to the next lesson. | |
38 | |
14347 | 39 3. Using the down key, move to lesson 1.2. |
1624 | 40 |
41 NOTE: If you are ever unsure about something you typed, press <ESC> to place | |
42 you in Normal mode. Then retype the command you wanted. | |
43 | |
44 NOTE: The cursor keys should also work. But using hjkl you will be able to | |
45 move around much faster, once you get used to it. Really! | |

230 | |
231 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
232 Lesson 2.3: ON OPERATORS AND MOTIONS | |
233 | |
234 | |
235 Many commands that change text are made from an operator and a motion. | |
236 The format for a delete command with the d delete operator is as follows: | |
237 | |
238 d motion | |
239 | |
240 Where: | |
241 d - is the delete operator. | |
242 motion - is what the operator will operate on (listed below). | |
243 | |
244 A short list of motions: | |
245 w - until the start of the next word, EXCLUDING its first character. | |
246 e - to the end of the current word, INCLUDING the last character. | |
247 $ - to the end of the line, INCLUDING the last character. | |
248 | |
249 Thus typing de will delete from the cursor to the end of the word. | |
250 | |
251 NOTE: Pressing just the motion while in Normal mode without an operator will | |
252 move the cursor as specified. | |
253 | |
254 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
255 Lesson 2.4: USING A COUNT FOR A MOTION | |
256 | |
257 | |
258 ** Typing a number before a motion repeats it that many times. ** | |
259 | |
14347 | 260 1. Move the cursor to the start of the line below marked --->. |
1624 | 261 |
262 2. Type 2w to move the cursor two words forward. | |
263 | |
264 3. Type 3e to move the cursor to the end of the third word forward. | |
265 | |
266 4. Type 0 (zero) to move to the start of the line. | |
267 | |
268 5. Repeat steps 2 and 3 with different numbers. | |
269 | |
270 ---> This is just a line with words you can move around in. | |
271 | |
14347 | 272 6. Move on to lesson 2.5. |
1624 | 273 |
274 | |
275 | |
276 | |
277 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
278 Lesson 2.5: USING A COUNT TO DELETE MORE | |
279 | |
280 | |
281 ** Typing a number with an operator repeats it that many times. ** | |
282 | |
283 In the combination of the delete operator and a motion mentioned above you | |
284 insert a count before the motion to delete more: | |
285 d number motion | |
286 | |
287 1. Move the cursor to the first UPPER CASE word in the line marked --->. | |
288 | |
14347 | 289 2. Type d2w to delete the two UPPER CASE words. |
1624 | 290 |
291 3. Repeat steps 1 and 2 with a different count to delete the consecutive | |
14347 | 292 UPPER CASE words with one command. |
1624 | 293 |
294 ---> this ABC DE line FGHI JK LMN OP of words is Q RS TUV cleaned up. | |

301 Lesson 2.6: OPERATING ON LINES | |
302 | |
303 | |
304 ** Type dd to delete a whole line. ** | |
305 | |
306 Due to the frequency of whole line deletion, the designers of Vi decided | |
307 it would be easier to simply type two d's to delete a line. | |
308 | |
309 1. Move the cursor to the second line in the phrase below. | |
310 2. Type dd to delete the line. | |
311 3. Now move to the fourth line. | |
312 4. Type 2dd to delete two lines. | |
313 | |
314 ---> 1) Roses are red, | |
315 ---> 2) Mud is fun, | |
316 ---> 3) Violets are blue, | |
317 ---> 4) I have a car, | |
318 ---> 5) Clocks tell time, | |
319 ---> 6) Sugar is sweet | |
320 ---> 7) And so are you. | |
321 | |

324 Lesson 2.7: THE UNDO COMMAND | |
325 | |
326 | |
327 ** Press u to undo the last commands, U to fix a whole line. ** | |
328 | |
329 1. Move the cursor to the line below marked ---> and place it on the | |
330 first error. | |
331 2. Type x to delete the first unwanted character. | |
332 3. Now type u to undo the last command executed. | |
333 4. This time fix all the errors on the line using the x command. | |
334 5. Now type a capital U to return the line to its original state. | |
335 6. Now type u a few times to undo the U and preceding commands. | |
336 7. Now type CTRL-R (keeping CTRL key pressed while hitting R) a few times | |
337 to redo the commands (undo the undo's). | |
338 | |
339 ---> Fiix the errors oon thhis line and reeplace them witth undo. | |

359 [number] - is an optional count to repeat the motion | |
360 motion - moves over the text to operate on, such as w (word), | |
361 $ (to the end of line), etc. | |
362 | |
363 6. To move to the start of the line use a zero: 0 | |
364 | |
365 7. To undo previous actions, type: u (lowercase u) | |
366 To undo all the changes on a line, type: U (capital U) | |

508 Lesson 4.2: THE SEARCH COMMAND | |
509 | |
510 | |
511 ** Type / followed by a phrase to search for the phrase. ** | |
512 | |
513 1. In Normal mode type the / character. Notice that it and the cursor | |
514 appear at the bottom of the screen as with the : command. | |
515 | |
516 2. Now type 'errroor' <ENTER>. This is the word you want to search for. | |
517 | |
518 3. To search for the same phrase again, simply type n . | |
519 To search for the same phrase in the opposite direction, type N . | |
520 | |
521 4. To search for a phrase in the backward direction, use ? instead of / . | |
522 | |
523 5. To go back to where you came from press CTRL-O (Keep Ctrl down while | |
524 pressing the letter o). Repeat to go back further. CTRL-I goes forward. | |
525 | |
526 ---> "errroor" is not the way to spell error; errroor is an error. | |
527 NOTE: When the search reaches the end of the file it will continue at the | |
528 start, unless the 'wrapscan' option has been reset. | |
529 | |

541 | |
542 4. Type % to move the cursor to the other matching bracket. | |
543 | |
544 5. Move the cursor to another (,),[,],{ or } and see what % does. | |
545 | |
546 ---> This ( is a test line with ('s, ['s ] and {'s } in it. )) | |
547 | |
548 | |
549 NOTE: This is very useful in debugging a program with unmatched parentheses! | |
550 | |

558 | |
559 1. Move the cursor to the line below marked --->. | |
560 | |
14347 | 561 2. Type :s/thee/the <ENTER> . Note that this command only changes the |
1624 | 562 first occurrence of "thee" in the line. |
563 | |
564 3. Now type :s/thee/the/g . Adding the g flag means to substitute | |
565 globally in the line, change all occurrences of "thee" in the line. | |
566 | |
567 ---> thee best time to see thee flowers is in thee spring. | |
568 | |
569 4. To change every occurrence of a character string between two lines, | |
570 type :#,#s/old/new/g where #,# are the line numbers of the range | |
571 of lines where the substitution is to be done. | |
572 Type :%s/old/new/g to change every occurrence in the whole file. | |
573 Type :%s/old/new/gc to find every occurrence in the whole file, | |
574 with a prompt whether to substitute or not. | |
575 | |
576 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
577 Lesson 4 SUMMARY | |
578 | |
579 | |
580 1. CTRL-G displays your location in the file and the file status. | |
581 G moves to the end of the file. | |
582 number G moves to that line number. | |
583 gg moves to the first line. | |
584 | |
585 2. Typing / followed by a phrase searches FORWARD for the phrase. | |
586 Typing ? followed by a phrase searches BACKWARD for the phrase. | |
587 After a search type n to find the next occurrence in the same direction | |
588 or N to search in the opposite direction. | |
589 CTRL-O takes you back to older positions, CTRL-I to newer positions. | |
590 | |
591 3. Typing % while the cursor is on a (,),[,],{, or } goes to its match. | |

600 Lesson 5.1: HOW TO EXECUTE AN EXTERNAL COMMAND | |
601 | |
602 | |
603 ** Type :! followed by an external command to execute that command. ** | |
604 | |
605 1. Type the familiar command : to set the cursor at the bottom of the | |
606 screen. This allows you to enter a command-line command. | |
607 | |
608 2. Now type the ! (exclamation point) character. This allows you to | |
609 execute any external shell command. | |
610 | |
611 3. As an example type ls following the ! and then hit <ENTER>. This | |
612 will show you a listing of your directory, just as if you were at the | |
613 shell prompt. Or use :!dir if ls doesn't work. | |
614 | |
615 NOTE: It is possible to execute any external command this way, also with | |
616 arguments. | |
617 | |
618 NOTE: All : commands must be finished by hitting <ENTER> | |
619 From here on we will not always mention it. | |
620 | |

623 Lesson 5.2: MORE ON WRITING FILES | |
624 | |
625 | |
14347 | 626 ** To save the changes made to the text, type :w FILENAME ** |
1624 | 627 |
628 1. Type :!dir or :!ls to get a listing of your directory. | |
629 You already know you must hit <ENTER> after this. | |
630 | |
631 2. Choose a filename that does not exist yet, such as TEST. | |
632 | |
633 3. Now type: :w TEST (where TEST is the filename you chose.) | |
634 | |
635 4. This saves the whole file (the Vim Tutor) under the name TEST. | |
636 To verify this, type :!dir or :!ls again to see your directory. | |
637 | |
638 NOTE: If you were to exit Vim and start it again with vim TEST , the file | |
639 would be an exact copy of the tutor when you saved it. | |
640 | |
14347 | 641 5. Now remove the file by typing (Windows): :!del TEST |
1624 | 642 or (Unix): :!rm TEST |
643 | |
644 | |
645 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
646 Lesson 5.3: SELECTING TEXT TO WRITE | |

|
659 that you see :'<,'>w TEST before you press <ENTER>. |
1624 | 660 |
3847 | 661 5. Vim will write the selected lines to the file TEST. Use :!dir or :!ls |
1624 | 662 to see it. Do not remove it yet! We will use it in the next lesson. |
663 | |
664 NOTE: Pressing v starts Visual selection. You can move the cursor around | |
665 to make the selection bigger or smaller. Then you can use an operator | |
666 to do something with the text. For example, d deletes the text. | |
667 | |
668 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
669 Lesson 5.4: RETRIEVING AND MERGING FILES | |
670 | |
671 | |
672 ** To insert the contents of a file, type :r FILENAME ** | |
673 | |
674 1. Place the cursor just above this line. | |
675 | |
14347 | 676 NOTE: After executing Step 2 you will see text from lesson 5.3. Then move |
1624 | 677 DOWN to see this lesson again. |
678 | |
679 2. Now retrieve your TEST file using the command :r TEST where TEST is | |
680 the name of the file you used. | |
681 The file you retrieve is placed below the cursor line. | |
682 | |
683 3. To verify that a file was retrieved, cursor back and notice that there | |
14347 | 684 are now two copies of lesson 5.3, the original and the file version. |
1624 | 685 |
686 NOTE: You can also read the output of an external command. For example, | |
687 :r !ls reads the output of the ls command and puts it below the | |
688 cursor. | |
689 | |
690 | |
691 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
692 Lesson 5 SUMMARY | |
693 | |
694 | |
695 1. :!command executes an external command. | |
696 | |
697 Some useful examples are: | |
14347 | 698 (Windows) (Unix) |
1624 | 699 :!dir :!ls - shows a directory listing. |
700 :!del FILENAME :!rm FILENAME - removes file FILENAME. | |
701 | |
702 2. :w FILENAME writes the current Vim file to disk with name FILENAME. | |
703 | |
704 3. v motion :w FILENAME saves the Visually selected lines in file | |
705 FILENAME. | |
706 | |
707 4. :r FILENAME retrieves disk file FILENAME and puts it below the | |
708 cursor position. | |
709 | |
710 5. :r !dir reads the output of the dir command and puts it below the | |
711 cursor position. | |

1624 | 754 ---> This li will allow you to pract appendi text to a line. |
755 ---> This line will allow you to practice appending text to a line. | |
756 | |
757 NOTE: a, i and A all go to the same Insert mode, the only difference is where | |
758 the characters are inserted. | |
759 | |
760 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
761 Lesson 6.3: ANOTHER WAY TO REPLACE | |
762 | |
763 | |
764 ** Type a capital R to replace more than one character. ** | |
765 | |

853 Lesson 7.1: GETTING HELP | |
854 | |
855 | |
856 ** Use the on-line help system ** | |
857 | |
858 Vim has a comprehensive on-line help system. To get started, try one of | |
859 these three: | |
860 - press the <HELP> key (if you have one) | |
861 - press the <F1> key (if you have one) | |
862 - type :help <ENTER> | |
863 | |
864 Read the text in the help window to find out how the help works. | |
865 Type CTRL-W CTRL-W to jump from one window to another. | |
866 Type :q <ENTER> to close the help window. | |
867 | |
868 You can find help on just about any subject, by giving an argument to the | |
869 ":help" command. Try these (don't forget pressing <ENTER>): | |
870 | |
871 :help w | |
872 :help c_CTRL-D | |
873 :help insert-index | |
874 :help user-manual | |
875 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
876 Lesson 7.2: CREATE A STARTUP SCRIPT | |
877 | |
878 | |
879 ** Enable Vim features ** | |
880 | |
881 Vim has many more features than Vi, but most of them are disabled by | |
882 default. To start using more features you have to create a "vimrc" file. | |
883 | |
884 1. Start editing the "vimrc" file. This depends on your system: | |
885 :e ~/.vimrc for Unix | |
14347 | 886 :e $VIM/_vimrc for Windows |
1624 | 887 |
888 2. Now read the example "vimrc" file contents: | |
889 :r $VIMRUNTIME/vimrc_example.vim | |
890 | |
891 3. Write the file with: | |
892 :w | |
893 | |
894 The next time you start Vim it will use syntax highlighting. | |
895 You can add all your preferred settings to this "vimrc" file. | |
896 For more information type :help vimrc-intro | |
897 | |
898 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
899 Lesson 7.3: COMPLETION | |
900 | |
901 | |
902 ** Command line completion with CTRL-D and <TAB> ** | |
903 | |
904 1. Make sure Vim is not in compatible mode: :set nocp | |
905 | |
906 2. Look what files exist in the directory: :!ls or :!dir | |
907 | |
908 3. Type the start of a command: :e | |
909 | |
910 4. Press CTRL-D and Vim will show a list of commands that start with "e". | |
911 | |
14347 | 912 5. Type d<TAB> and Vim will complete the command name to ":edit". |
1624 | 913 |
914 6. Now add a space and the start of an existing file name: :edit FIL | |
915 | |
916 7. Press <TAB>. Vim will complete the name (if it is unique). | |
917 | |
918 NOTE: Completion works for many commands. Just try pressing CTRL-D and | |
919 <TAB>. It is especially useful for :help . | |
920 | |

922 Lesson 7 SUMMARY | |
923 | |
924 | |
14347 | 925 1. Type :help or press <F1> or <HELP> to open a help window. |
1624 | 926 |
927 2. Type :help cmd to find help on cmd . | |
928 | |
14347 | 929 3. Type CTRL-W CTRL-W to jump to another window. |
1624 | 930 |
14347 | 931 4. Type :q to close the help window. |
1624 | 932 |
933 5. Create a vimrc startup script to keep your preferred settings. | |
934 | |
935 6. When typing a : command, press CTRL-D to see possible completions. | |
936 Press <TAB> to use one completion. | |

945 | |
946 This concludes the Vim Tutor. It was intended to give a brief overview of | |
947 the Vim editor, just enough to allow you to use the editor fairly easily. | |
948 It is far from complete as Vim has many many more commands. Read the user | |
949 manual next: ":help user-manual". | |
