Whether you're new to vi or just looking for a refresher, these 11 tips will enhance how you use it. - -### Editing - -Editing a long script can be tedious, especially when you need to edit a line so far down that it would take hours to scroll to it. Here's a faster way. - - 1. The command `:set number` numbers each line down the left side. - -![](https://opensource.com/sites/default/files/styles/panopoly_image_original/public/u128651/setnum.png?itok=sFVA97mG) - -You can directly reach line number 26 by opening the file and entering this command on the CLI: `vi +26 sample.txt`. To edit line 26 (for example), the command `:26` will take you directly to it. - -![](https://opensource.com/sites/default/files/styles/panopoly_image_original/public/u128651/number.png?itok=d7FE0LL3) - -### Fast navigation - - 2. `i` changes your mode from "command" to "insert" and starts inserting text at the current cursor position. - 3. `a` does the same, except it starts just after the current cursor position. - 4. `o` starts the cursor position from the line below the current cursor position. - - - -### Delete - -If you notice an error or typo, being able to make a quick fix is important. Good thing vi has it all figured out. - -Understanding vi's delete function so you don't accidentally press a key and permanently remove a line, paragraph, or more, is critical. - - 5. `x` deletes the character under the cursor. - 6. `dd` deletes the current line. (Yes, the whole line!) - - - -Here's the scary part: `30dd` would delete 30 lines starting with the current line! Proceed with caution when using this command. - -### Search - -You can search for keywords from the "command" mode rather than manually navigating and looking for a specific word in a plethora of text. - - 7. `:/` searches for the word mentioned in the `< >` space and takes your cursor to the first match. - 8. To navigate to the next instance of that word, type `n`, and keep pressing it until you get to the match you're looking for. - - - -For example, in the image below I searched for `ssh`, and vi highlighted the beginning of the first result. - -![](https://opensource.com/sites/default/files/styles/panopoly_image_original/public/u128651/ssh-search.png?itok=tJ-7FujH) - -After I pressed `n`, vi highlighted the next instance. - -![](https://opensource.com/sites/default/files/styles/panopoly_image_original/public/u128651/n-search.png?itok=wU-u3LiI) - -### Save and exit - -Developers (and others) will probably find this next command useful. - - 9. `:x` saves your work and exits vi. - -![](https://opensource.com/sites/default/files/styles/panopoly_image_original/public/u128651/x.png?itok=kfoHx84m) - - 10. If you think every nanosecond is worth saving, here's a faster way to shift to terminal mode in vi. Instead of pressing `Shift+:` on the keyboard, you can press `Shift+q` (or Q, in caps) to access [Ex mode][2], but this doesn't really make any difference if you just want to save and quit by typing `x` (as shown above). - - - -### Substitution - -Here is a neat trick if you want to substitute every occurrence of one word with another. For example, if you want to substitute "desktop" with "laptop" in a large file, it would be monotonous and waste time to search for each occurrence of "desktop," delete it, and type "laptop." - - 11. The command `:%s/desktop/laptop/g` would replace each occurrence of "desktop" with "laptop" throughout the file; it works just like the Linux `sed` command. - - - -In this example, I replaced "root" with "user": - -![](https://opensource.com/sites/default/files/styles/panopoly_image_original/public/u128651/subs-command.png?itok=M8MN72sp) - -![](https://opensource.com/sites/default/files/styles/panopoly_image_original/public/u128651/subs-result.png?itok=34zzVdUt) - -These tricks should help anyone get started using vi. Are there other neat tips I missed?
