You can use the: s command to replace a string in Vi/vim. The command has a number of different details of how to use the method, you can implement complex functions, record several here, convenient later query.

: s/vivian/sky/replaces the current line the first Vivian is sky

: S/vivian/sky/g replaces the current line all Vivian are sky

: N, $s/vivian/sky/replaces the first Vivian of each row in the nth row to the last row is sky

N, $s/vivian/sky/g replace the nth line to the last row, all Vivian is sky  for each row;
 
n is a number, if N is., which means starting from the current line to the last row  
:%s/vivian/sky/(equivalent to: g/vivian/s//sky/) replaces the first Vivian of each row with sky 
Span style= "FONT-SIZE:14PX;" >  
:%s/vivian/sky/g (equivalent to: g/vivian/s//sky/g) replaces all Vivian in each row as sky 
Span style= "FONT-SIZE:14PX;" >  
You can use # as a delimiter, at which time the middle appears/does not act as a delimiter  
& nbsp
: s#vivian/#sky/# Replace the current row the first vivian/is sky/ 
 

5. Delete the ^m in the text

Problem description: For line breaks, the window is replaced with a carriage return (0a0d) to indicate that Linux is a carriage return (0A) to represent. This way, when you copy a file on a window to UNIX, there is always a ^m. Write a shell or C program that uses a newline character (0D) that filters Windows files under UNIX.

。 Using the command: Cat filename1 | tr-d "^v^m" > NewFile;

。 Use command: sed-e "s/^v^m//" filename > outputfilename. Note that in 1, 22 methods, ^v and ^m refer to Ctrl + V and ctrl+m. You have to do the input manually, not paste.

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

。 :%s/^m$//g

If the above method is useless, the correct workaround is: [Page]

。 tr-d \ "\\r\" < src >dest

。 tr-d \ "\\015\" dest

。 Strings A>b
6. Replacement Confirmation
There are many times when a character (string) is required to be replaced in some position in the article, while other locations are not replaced by the selected action, which requires the user to confirm, and the VI lookup replaces the same support
For example
: S/vivian/sky/g replaces the current line all Vivian are sky
Adding a letter C to the command can be implemented, namely: S/VIVIAN/SKY/GC
As implies, C is the abbreviation of confirm

7. Other

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

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

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

：。 , $ s/str1/str2/g Replaces all occurrences of the current line to the end of the string with the string str2 str1

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

: g/str1/s//str2/g function Ibid.

You can see from the Replace command above that the G is placed at the end of the command to replace each occurrence of the search string, without g, which means that only the search

Replace the first occurrence of the string, and G at the beginning of the command to replace all rows in the body that contain the search string
