The man system is a powerful help system under Linux that can provide almost all the help information to the system users and programmers.
These help information comes primarily from the selfless contributions of many document maintainers in the Linux open source world.
The man system itself has some basic usage tips, excerpt from the following:
1. Open the Help information for XXX
Mans XXX
2. View the help information for a shell command
Man 1 xxx
Man classifies all the help information, using numbers to mark each category:
In the above example, because we are looking for the shell command usage, so the choice is category 1, if you want to check the use of C library functions, then the category that needs to be used is 3, such as:
Mans 3 fopen
3. Exit Man system input Q
4. Search for input in the man content:/xxx
Next: N
Previous: P
Memory method: Consistent with Vim's search usage
5. Jump to the start of the man content input: g
Similar to the use of vim
6. Jump to the end of the man content input: G
Consistent with the use of vim
