Looking at a real expert Operation command line is definitely a good experience-the cursor travels back and forth between words, and the command line scrolls differently. Developers who are strongly adapting to GUI programs here try to work under the prompt. But things are not so simple, or need to know "how to do".
To jump between words, use CTRL + around keys. CTRL + a jumps to the beginning of the line, Ctrl+e jumps to the end of the page. Ctrl+u Delete the text that precedes the current cursor ctrl+k-Delete the text after the current cursor ctrl+w and alt+d-Delete the current word, w delete the character of the word in front of the cursor, d delete the following character alt+backsapce-delete the word after the current cursor , if you delete the error, use Ctrl+y for recovery ctrl+l to clear the screen.
