Linux Learning Log (Basic)----Vim's editing mode and last-line mode __linux

    4, vim switch from command mode to edit mode A: Insert large A from the back of the cursor: End of line insert I: With a, insert large I: start at the beginning of the cursor Insert O: start at the beginning of the current cursor Insert Big O: Another The line begins to insert S: Eats the current cursor-covered character and begins inserting the big s: Eat one line and start inserting 5. The last line mode of VIM uses ESC to exit edit mode using: Enter the last line mode in last line mode, direct Enter a number, jump back to the corresponding line number WQ: Save and exit Q: Exit, if made changes, prompts whether to save, if not modified, will directly exit Q.  : Exit Do not save W: Save do not exit X: function is equivalent to WQ, save and exit in command mode there is also an exit and save command: Shift + ZZ, but he and Wq are different WQ will create a new file, shift 
        + ZZ does not, so you can directly use VI to create a new file without touch command Eg:vi test Wq exit and save, the current directory will have a new file test, use SHIFT + ZZ is no such effect
