This is the virtual machine I built myself. The command in shell starts [rht-vmctl strat workstation] directly, and workstation is the virtual machine I built.

The first is the vim operation:

Vim is divided into three modes: command mode, insert mode and exit mode.

Use [vim file name] to open the file to be edited, [I] enter insert mode, launch [Esc] when finished, and finally [: wq] save and exit.

"what is explained is that the final exit vim is divided into several other modes. [: Q] only exit, [: Q!] does not save editing content forced exit, [: wq!] permission allows forced editing and saving of read-only files."

[: set] parameter settings are divided into temporary vim, current user's personal parameter settings [vim ~ / .vimrc], and full-user parameter settings [vim / etc/vimrc].

[/ character] can perform a character search, [n] look down for the searched characters, [N] look up for the searched characters, and [: number] the cursor moves to a specific number of lines.

Vim character management, divided into copy "[yl] copy current character, [yw] copy current word, [yy] copy current line", delete "[dl] delete current character, [dw] delete current word, [dd] delete current line", cut and paste "[cl] cut and paste current character, [cw] cut and paste current word, [cc] cut and paste current line", [p] paste, [u] undo, [Ctrl r] return revocation.

Visual mode operation, [Ctrl v] enters visualization mode, moves the cursor up and down the selection, then [I] goes in and out of editing, and then [Esc] exits, and the edited content is applied to the selected line.

Split screen operation: [Ctrl w] [s] or [ctrl w] [v] split screen, use [Ctrl w] plus keys to switch different windows, the content edited in each window will be applied to all windows, and each window can be named and saved separately, [:-sp] can open and edit other files at the same time, [Ctrl w] [c] can close redundant windows after split screen.

In command mode, the cursor moves, [gg] moves to the last line, [G] moves to the front line, and [: number] moves to the specified number of lines.

Shortcut key to enter insert mode: [I] move the cursor to the front of the line to insert, [I] the current position to insert, [A] move the cursor to the last start of the line, [a] insert after the current word, [O] insert a line on the line, [o] insert a row under the line, [S] delete the line insert, [s] delete the word insert.

The above is my summary after learning to edit vim. It may not be very comprehensive, it is purely personal understanding.
