Don't know how to specify file editor with red command of linux? In fact, it is not difficult to solve this problem. Let Xiaobian take you to learn how to solve it together. I hope you will gain a lot after reading this article.

The red command is used to edit by reading the specified file. The red command edits the contents of the input file by line. It is a line editor and a text editor.

The red command, which can be used not only in bash but also in script files, reads the contents of the entire file into its own buffer, performs specified operations on that copy, and optionally writes the buffer to disk.

Note that when editing with the red command, you can't see the file content. Be sure to carefully check the input content to ensure its correctness, and avoid repeatedly going back and forth between the editing state and the command line state, which will waste a lot of time.

Syntax format: red[parameters] [file]
