# vim
|
|
|
|
> Vi IMproved, a programmer's text editor, provides several modes for different kinds of text manipulation.
|
|
> Pressing `i` enters edit mode. `<Esc>` goes back to normal mode, which doesn't allow regular text insertion.
|
|
> Homepage: <https://www.vim.org>.
|
|
|
|
- Open a file:
|
|
|
|
`vim {{file}}`
|
|
|
|
- Enter text editing mode (insert mode):
|
|
|
|
`<Esc>i`
|
|
|
|
- Copy ("yank") or cut ("delete") the current line (paste it with `P`):
|
|
|
|
`<Esc>{{yy|dd}}`
|
|
|
|
- Undo the last operation:
|
|
|
|
`<Esc>u`
|
|
|
|
- Search for a pattern in the file (press `n`/`N` to go to next/previous match):
|
|
|
|
`<Esc>/{{search_pattern}}<Enter>`
|
|
|
|
- Perform a regex substitution in the whole file:
|
|
|
|
`<Esc>:%s/{{pattern}}/{{replacement}}/g<Enter>`
|
|
|
|
- Save (write) the file, and quit:
|
|
