Common VI skills

The VI command is the most commonly used file editing command in the Unix/Linux World, but many people are not used to it because of its many command sets, in fact, you only need to master the basic commands and use them flexibly. Then you will find its advantages and will gradually enjoy using this method. This article aims to introduce some of the most common commands and advanced application skills of VI.

1. Introduction to basic commands

---- 1. cursor command

K, J, H, l -- move the cursor up, down, left, and right. Although you can use the four optical keys on the right of the keyboard in Linux, it is very useful to remember these four commands. These four keys are the basic locations where the right hand is placed on the keyboard.
Ng -- jump command. N indicates the number of rows. This command immediately redirects the cursor to the specified row.
CTRL + G -- number of rows and columns at the cursor position.
W, B -- let the cursor skip a word forward or backward.
---- 2. Edit the command
I, A, R -- insert character commands (I = insert, A = append, r = replace) before, after, and at the cursor ).
CW, DW -- change (replace)/command for deleting words where the cursor is located (C = change, D = delete ).
X, d $, and DD -- delete a character, delete all characters from the cursor's position to the end of the line, and delete the entire line.
---- 3. Search for commands
----/String ,? String -- the command used to search for the corresponding string from the cursor to the back or forward position.
---- 4. copy Copy command
---- YY, p -- command used to copy a row to the clipboard or retrieve the content in the clipboard.

Ii. FAQs and application skills

---- 1. Read the content in/etc/passwd in a new file and retrieve the username section.
---- VI File
----: R/etc/passwd read/etc/passwd at the cursor position in the opened file
----: % S/:. * // G delete all parts after the user name in/etc/passwd from the colon until the end of the line.
---- You can also read the file content after the specified row number. For example, you can use the command ": 3R/etc/passwd" to read all the content of/etc/passwd from line 1 of the new file.
---- You can also use the following method to delete all blank lines in the file and comment lines starting.
---- # Cat squid. conf. Default | grep-V ^ $ | grep-V ^ #

---- 2. After opening a file and editing it, the logged-on user does not have the write permission for the file and cannot store the disk. You need to save the modifications to the temporary file.
---- VI File
----: W/tmp/1 save all the modifications you have made. You can also save some of the modifications to a temporary file. For example, you can only save 20th ~ Store the contents between 59 rows into a file/tmp/1. You can type the following command.
---- VI File
----: 20, 59 w/tmp/1

---- 3. Use VI to edit a file, but you need to delete the contents of a large segment.
---- Use the edit command "VI file" to open the file, move the cursor to the row to be deleted, press Ctrl + G to display the row number, and then press Ctrl + G to the end, displays the row number at the end of the file.
----: Assume that the number of rows obtained twice in 23,104 5d is 23 and 1045, all contents in this period will be deleted, you can also mark the start and end lines to be deleted with the MA and MB commands, and then use the ": A, BD" command to delete them.

---- 4. Add strings at the beginning or end of the row or several lines of the entire file.
---- VI File
----: 3, $ S/^/some string/Insert "some string" at the beginning of the line from the first row to the last row of the file ".
---- % S/$/some string/g Add "some string" at the end of each row of the entire file ".
---- % S/string1/string2/g Replace "string1" with "string2" in the entire file ".
----: 3rd S/string1/string2/Replace "string1" in rows 7th to of the file with "string2 ".
---- Note: S is substitute, % indicates all rows, and G indicates global.

---- 5. Edit two files at the same time, copy the text in one file and paste it into another file.
---- VI file1 file2
---- YY copies the row at the cursor of file 1
----: N switch to file 2 (n = NEXT)
---- P paste the copied row at the cursor of file 2
----: N switch back to file 1

---- 6. Replace the path in the file.
---- Use the command ": % s #/usr/bin # G" to replace all the paths/usr/bin in the file with/bin. You can also run the command ": % S/usr/bin // bin/g", where "" is an escape character, it indicates that the subsequent "/" character is a meaningful character, not a separator.
