Vim multi-line indent and advanced commands

Vim Multiple Line Indent tips 1. Enter the visual state by V, select multiple lines and indent or indent with > or <

2. Automatic indent typesetting is usually used according to language features: in the command state = = Two for the current line, or for multiple rows with n== (n is the natural number) for automatic indentation from the current line below n rows. You can try to indent code arbitrarily and then use n== typesetting, equivalent to the General IDE in the code format. Use GG=G to format the entire piece of code. 3.gg shift+g 4. Full text replaces%s/source/dist/g or: 1,$ s/source/dist/g: s/vivian/sky/replaces the current line the first Vivian for Sky

: S/vivian/sky/g replaces current line all Vivian for Sky

: N, $s/vivian/sky/replaces the first n line to the top Vivian for each line in the last line of Sky

: N, $s/vivian/sky/g replaces the first n line to each line in the last line all Vivian for Sky

N is a number, and if N is., it means starting from the current line to the last line

:%s/vivian/sky/(equivalent to: g/vivian/s//sky/) replaces the first Vivian of each line as Sky

:%s/vivian/sky/g (equivalent to: g/vivian/s//sky/g) replaces all Vivian in each row as Sky

You can use # as a separator, in which the middle appears/is not a separator

: s#vivian/#sky/# Replace the first vivian/of the current line as sky/

:%s+/oradata/apras/+/user01/apras1+ (using + to replace/):/oradata/apras/replaced with/user01/apras1/

1.:s/vivian/sky/replaces current line first Vivian for Sky

: S/vivian/sky/g replaces current line all Vivian for Sky

2.: N, $s/vivian/sky/replaces the first n line to the top of each line in the last line Vivian for Sky

: N, $s/vivian/sky/g replaces the first n line to each line in the last line all Vivian for Sky

(n is a number, if N is., which means starting from the current line to the last line)

3.:%s/vivian/sky/(equivalent to: g/vivian/s//sky/) replaces the first Vivian of each line for Sky

:%s/vivian/sky/g (equivalent to: g/vivian/s//sky/g) replaces all Vivian in each row as Sky

4. You can use # as a separator, which appears in the middle/not as a separator

: s#vivian/#sky/# Replace the first vivian/of the current line as sky/

5. Delete the ^m in the text

Problem Description: For newline, window with carriage return Line (0A0D) to express, Linux is a carriage return (0A) to express. This way, there will always be a ^m when you copy files on Windows to UNIX. Write a shell or C program that filters a line break (0D) for a window file under UNIX.

· Using commands: Cat filename1 | tr-d "^v^m" > NewFile;

· Use command: sed-e "s/^v^m//" filename > OutputFileName. It should be noted that in 1, 22 of the methods, ^v and ^m refer to Ctrl + V and ctrl+m. You have to enter it manually instead of pasting it.

· In VI Processing: First use VI to open the file, and then press the ESC key, and then enter the command:%s/^v^m//.

· :%s/^m$//g

If the above method is useless, the correct solution is:

· Tr-d "\ r" < src >dest

· Tr-d "\015" dest

· Strings A>b

6. Other

Use the: s command to implement a string substitution. The specific uses include:

: s/str1/str2/replaces the first occurrence of a string with a string str2 str1

: S/str1/str2/g replaces all occurrences of the string in a line with a string str2 str1

:., $ s/str1/str2/g Replaces all occurrences of the body's current line to the end with a string str2 str1

: 1,$ s/str1/str2/g replaces all occurrences of a string in the body with a string str2 str1

: g/str1/s//str2/g function ditto

From the above substitution command you can see that G is placed at the end of the command to replace each occurrence of the search string;

The first occurrence of the

string is substituted; G is placed at the beginning of the command to replace all the lines in the body that contain the search string.
