Vim text editor is used for creating, editing and perform other operations in a text file. Common modes in Vim i.e.
- Normal Mode : Hit the Esc key to enter Normal mode.
- Command Mode : Type colon ( : ) in the normal mode to go to this mode.
- Insert Mode : Type i in the normal mode to go to insert mode.
.(dot) repeat last command.
Normal Mode Commands
- Show line number
- Copy text
Select text and press Ctrl + C
- Go to line number
For instance, if you wanted to go to line 14, could press Esc and then enter
- Search some text
Enter /pattern, replacing pattern with the text for which you want to search forward. For example, to find every instance of the word “blimp”, enter:
To search for word, enter
/\<word\>in Normal Mode.
\<means beginning of a word, and
\>means the end of a word. Enter n for next and N for previous search result.
- Search for text in the document, going backwards.
- Find text and replace
Search through the entire document for text and replace it with replacement text. To check the text before replacement, use below command
- Go go end of file
- Go to end of cursor
Command Mode Options
- :q! to quit without saving (short for :quit!)
- :wq to write and quit
- :wq! to write and quit even if file has only read permission (if file does not have write permission: force write)
- :x to write and quit (similar to :wq, but only write if there are changes)
- :qa to quit all (short for :quitall)
- :cq to quit without saving and make Vim return non-zero error (i.e. exit with error)
Navigating In File
- h moves the cursor one character to the left.
- j moves the cursor down one line.
- k moves the cursor up one line.
- l moves the cursor one character to the right.
- 0 moves the cursor to the beginning of the line.
- $ moves the cursor to the end of the line.
- w move forward one word.
- b move backward one word.
- G move to the end of the file.
- gg move to the beginning of the file.
