Okay I am exaggerating a lot here. ?
Recently, when I was asked by the boss at the office to learn Vim (as I had to navigate through an
ssh server), I decided to finish my unfinished business with Vim.
Which brought me here on Medium, to write about Vim. As a wise man once posted on Facebook, sharing knowledge is power.
So, open up your terminal and let’s talk about it.
Step 1: Install Vim
I am assuming you have
bash and you are a Linux user. I hope there are similar ways for Windows users to install Vim.
- On your terminal, write:
sudo apt-get update.
- Install Vim using:
sudo apt-get install vim. That’s it.
Step 2: Initiate Vim
This is going to be fun!
vim mytext.txton terminal and hit enter.
- You will see something like the following picture. Remember I am using a special tool called
vimrc. That’s why it will probably look different from your terminal. You can find
vimrchere. For now I guess you should ignore it.
- Don’t try to hit any keys randomly! At this very stage, your Vim is on Normal Mode. This mode is like an inspection mode, you basically navigate, delete, replace and do a bunch of other operations in this mode. You cannot write text when this mode is on.
- Let’s first exit from Vim without breaking anything!
:wq and hit enter.
What it does is, it writes the file on your disk and saves all the changes you made, and quits. If you do not want to save the changes, hit
Yep, that’s it!
Step 3: Write Something Using Vim
So now we will actually write something on Vim.
- In the previous step, as you have seen, we were working on Normal Mode. You cannot really write inside your file when this mode is on. You have to switch to Insert Mode.
- To do that, all you need to do is type and hit
ifrom Normal Mode.
- Now you can simply type whatever you want.
- We want to save it, right? To save the change on the disk, hit
ESCto switch to Normal Mode. And type
:w. Or you can also write
:wqto write and quit.
- Feel like a scientist.
- When you are in Normal Mode, to move up-down-left-right, you should use:
Yeah this is so weird. But it is meant for convenience. I guess once you are very accustomed to the key bindings of Vim, you can realize that.
- You can use the arrow keys in Insert Mode to navigate.
- Assume you wish to append some text at the end of a particular line of your text file. Move the cursor to that particular line (of course in Normal Mode) and hit
Step 4: Edit the File
- Let’s assume we want to edit our previous text file. Say, you want to replace the word gray with blue.
To do this, of course you can go the Insert Mode and use backspace to remove and write whatever you want. But we can do it more smoothly in Normal Mode. Move your cursor to the beginning of the word you want to delete, and hit
- Then switch to Insert Mode and write blue.
- Now the problem is, our poem does not rhyme! We should make it rhyme to claim a Nobel prize in Literature. Let’s delete the last line and write something worthy.
- To do that, in Normal Mode, move your cursor to the line you want to delete, and hit
- And switch to Insert Mode to write what you want.
Step 5: Some More Commands
- There is this command
:d$which deletes from the position of the cursor to the end of the line.
- You can easily do undo operation in Normal Mode. Just hit
u. To redo, hit
- Suppose you have made a typo somewhere and you want to replace one character with another one. You simply move the cursor on top of the character in Normal Mode, hit
rxwhere x is the character you want the current character to be replaced with.
- Or you just want to remove a character. Move the cursor on that and hit
