Vim garbled

Use VIM to open a blank document, and then paste the copied code into it, found that it has automatic indentation function, resulting in the pasted text line is more than one line on the right, looks mess. The quicker solution is to enter the document in command-line mode before pasting it

: Set Noai Nosi

Then press ' I ' to enter edit mode, and then paste the copied code content so that it does not automatically indent.

Sometimes, such a method is not good to use, you can try this:

: Set Paste

VIM encryption

Http://www.apelearn.com/bbs/thread-7750-1-1.html

Linux uses Vim/vi to encrypt and decrypt files

First, using VIM/VI encryption:

Advantages: After encryption, if you do not know the password, you can not see the plaintext, including the root user can not see;

Cons: Obviously let others know encryption, it is easy for others to destroy the encrypted files, including content destruction and deletion;

VI Editor believe that everyone is familiar with it, VI has a command is to encrypt the file, for example:

1) First create an experimental file under the root master directory/root/Text.txt:

[Email protected] ~]# Vim/vi text.txt

2) Enter the edit mode, press ESC after entering the content, then enter: X (note is the uppercase X), enter;

3) Then the system prompts you to enter the password, 2 times, as follows:

Enter Password: *******

Please enter again: *******

4) After saving the exit, now this file has been encrypted;

5) Use cat or more to view the contents of the file, displayed as garbled; re-edit this file with Vim/vi, will prompt for the password, if the password entered is incorrect, the same will be displayed as garbled!

Note: Do not forget the password after the file is encrypted!

Second, decrypt the files encrypted with VI (provided that you know the encrypted password):

1) Open the file with Vim/vi, such as Text.txt, to enter the correct password, and then at the time of editing, set the password to empty, by entering the following command:

: Set key=

Then directly enter, after saving the file, the file has been decrypted.

2) or This is OK:

After opening the file correctly with ": X" instruction, and then give a blank password can also. Save with "wq!" Save.

The two methods actually have the same effect.
