Recall last time
Last time I talked about three questions about soul ✊
Through these three questions, we can have a basic understanding of the command, let’s have a try!!
Our order clear this time is very simple
- The function of clear is to clear the screen
- Now I ask him three questions
In this way, we can have a basic understanding of clear. If you want to have a deeper understanding, you can consult the manual
Some documents can’t find the specific location, such as
- Say they’re shell build in command
Where are these orders?
- These commands are in this shell
- When the shell starts, it’s in memory
- So it’s called shell build in command
- There is no specific command file for the hard disk
- When did shell start?
- When terminal starts, load the shell code (such as Zsh) on the hard disk into the memory
- If you want to find the corresponding source code, go to the shell’s source code
This time our command clear is very simple, basic command operation we come here first, next time we summarize the previous content, goodbye!
