12, vim-read the file

The Read (: R) Read command reads the file into the work buffer. The new file does not overwrite any text in the work buffer, but is positioned after the address specified in the command (if no address is specified, it is the current row). Use address 0 to read a file into the beginning of the work buffer.

The read command syntax format is as follows:

: [address]r [filename]

1. If you omit address and filename, Vim reads from disk to the file that the user is editing, and the text content is on the next line of the current cursor.

2. Insert the contents of another file MyFile.txt in the current file Hello.txt:

Hello.txt its content is: Hello world!

MyFile.txt its contents are: This is a file.

#vim Hello.txt

#:r myfile.txt

The contents of the Hello.txt file are as follows:

Hello world!

This is a file.

3. Insert the contents of another file at the beginning of the current file:: 0r filename

We can use numbers to specify after which line to start inserting the contents of another file, for example: #vim hello.txt#:3r myfile.txt Inserts the contents of MyFile.txt into the 3rd line of the current file. Similarly, 0r myfile.txt inserts the contents of the myfile.txt into the No. 0 line of the current file, which is where the file first begins (although there is no real No. 0 line in the file, but we can take advantage of it). 13 vim-Write FilesWrite (: w) write command to write some or all of the contents of the work buffer to the file. The address can be used to write part of the work buffer to a file specified by the file name. If you do not specify an address or file, Vim writes the contents of the entire work buffer to the file being edited and updates the files on the disk.

The read command syntax format is as follows:

: [address]w [filename]

: [address]w[!] [FileName]

:[address]w>> [FileName]

Example:

: w MyFile.txt writes the contents of the current file to MyFile.txt if the file

Existing, the error will not modify the original content. : w! MyFile.txt writes the contents of the current file to MyFile.txt, overwriting the original content if the file already exists. : w >>myfile.txt appends the contents of the current file to the end of the file myfile.txt.
