And most of these commands can be combined, for example, the 9yy command means to copy 9 lines of content, 9 means the number of rows to be copied, the same 100dd means to delete 100 rows, when the number and command cooperation, more powerful than the simple command, similarly, the C command means erase, w means word is the word, Then CW means erase a word, c5w means delete 5 words and so on. By crafting these simple commands together, you can play a powerful, unimaginable function.

@x

A little explanation, when entered in normal mode: After QX, all your edits to the text will be recorded, enter Q again to exit the recording mode, and then enter @x to repeat the command just recorded, this command can be followed by numbers, indicating how many times to repeat, such as @x20, Can be repeated 20 times. This is very useful in batch processing of text.

Summary of common replacement patterns in vim

1, simple substitution expression

The Replace command can replace another word with one word in the full text:

:%s/four/4/g

The "%" range prefix indicates that substitutions are performed on all rows. The last "G" tag represents all the matching points in the replacement row. If you are only working on the current line, just remove the%

If you have a word like "thirtyfour", the above command will go wrong. In this case, the word will be replaced with "Thirty4″." To solve this problem, use "\<" to specify the beginning of the matching word:

:%s/\<four/4/g

Obviously, this will still make a mistake when dealing with "fourty". Use "\>" to solve this problem:

:%s/\<four\>/4/g

If you are coding, you may just want to replace "four" in the comment, while preserving the code. Since this is difficult to specify, you can add a "C" tag to the replacement command so that Vim prompts you before each replacement:

:%S/\&LT;FOUR\&GT;/4/GC

2. Remove extra spaces

To remove the extra space behind each line, you can execute the following command:

:%s/\s\+$//

The command indicates that the range is "%", so this works on the entire file. The match pattern for the "substitute" command is

"\s\+$". This represents one or more (\+) spaces (\s) before the end of the line ($). The "to" part of the Replace command is empty: "//". This will delete those matching whitespace characters.

3, matching repeatability mode

The asterisk item "*" Specifies that items in front of it can be repeated any time. So:

/a*

Match "A", "AA", "AAA", and so on. But also matches "" (empty string), because 0 times is also included. The asterisk "*" is applied only to the item that is immediately in front of it. So "ab*" matches "a", "AB", "ABB", "abbb", and so on. To repeat the entire string more than once, the string must be made up of an item. The way to form an item is to precede it with "\ (", followed by "\"). So this command:

/\ (ab\) *

Matches: "AB", "Abab", "Ababab", and so on. and also match "".

To avoid matching empty strings, use "\+". This means that the preceding item can be matched one or more times.

/ab\+

Match "AB", "ABB", "abbb", etc. It does not match "a" followed by "B".

To match an optional option, use "\=". For example:

/folders\=

Match "folder" and "Folders".

4, specify the number of repetitions

To match a specific number of times for an item, use the form "\{n,m}". where "n" and "M" are numbers. The item in front of it will be repeated "n" to "M" Times (|inclusive| contains "n" and "M"). For example:

/ab\{3,5}

Match "abbb", "abbbb" and "abbbbb".

When "n" is omitted, it is defaulted to zero. When "M" is omitted, the default is infinity. When ", M" is omitted, it means repeating exactly "n" Times. For example:

Pattern Match times

\{,4} 0,1,2,3 or 4

\{3,} 3,4,5, etc.

\{0,1} 0 or 1, same as \=

\{0,} 0 or more, same as *

\{1,} 1 or more, with \+

\{3} 3

5, multiple Select a match

In a lookup mode, the OR operator is "\|". For example:

/foo\|bar

This command matches "foo" or "bar". More choices can be attached to the back:

/one\|two\|three

Matches "One", "one", or "three".

To match its multiple repetitions, the entire decision structure must be placed between "\ (" and "\)":

/\ (foo\|bar\) \+

This command matches "foo", "Foobar", "Foofoo", "Barfoobar", and so on.

Let me give you an example:

/end\ (if\|while\|for\)

This command matches "endif", "Endwhile" and "ENDfor".
