Bytes -----------------------------------------------------------------------------------

When you use Putty to directly connect to Linux.

 

We can use VI to directly modify the file.

 

Below are some common commands ~

----------------------------------------------

1. Enter edit mode

(At the time of entry, it is actually in the command mode)

After ESS test.txt, press VI continuously to enter the VI editing mode.

========================================================== ====================

2. Save and exit

(The following command is in the ex escape mode)

Enter WQ in the command line to save and exit.

 

3. Discard the modification and exit directly.

: Q! You can exit and discard the modification.

 

(The following command is in the command mode)

4. query in VI Mode

/Sxz/session/timeout

In this way, the cursor will only stay on the first letter. For example, it will only stay on the S of the session.

 

However, there is a benefit: by N, You can query the next, n can find the previous.

In short, this query method is more convenient.

 

Note: The above 2 and 3 commands are all input in the command line. In editing mode,

Press ctrl C twice in a row to enter the command line. Enter the preceding command: Q! : WQ

(Pressing ctrl c twice in a row is actually from the input method to the command method and then to the ex escape method)

========================================================== ========================

5. You can also perform a query without entering the VI Mode.

However, we can query it when we exit VI Mode.

The query method is

Enter the command/sxz/timeout in the command line.

Here, sxz timeout is the string you want to query.

 

(Note: This method will mark all the strings you want to query, but you cannot query the next one. )
