Linux man and Linux man

Linux man and Linux man
The man system is a powerful help system in linux. It can provide almost all help information to system users and programmers.

The help information mainly comes from the selfless contribution of many document maintainers in the Linux open source world.

The man system has some basic usage skills. The following is an excerpt:

1. Open the help information of xxx

Man xxx

2. view the help information of a shell command

Man 1 xxx

Man classifies all help information, and each classification uses numbers to mark:

In the above example, because we want to check the shell command usage, we select class 1. If we want to check the usage of the C library function, the required category is 3, for example:

Man 3 fopen

3. Exit the man system and enter q.


4. Search for input in man content:/xxx
Next: n
Previous: p
Memory method: Consistent with VIM's search usage


5. Jump to the start of man content and enter: g

6. Jump to the end of man content and enter: G
