Man mkdir Tree's understanding

Man-k mkdir means to query mkdir related instructions, similar functions such as apropos mkdir, will list three instructions with mkdir;

The man command after its display explains a numeric parameter that indicates the specific range of positioning:

The number "1" represents a user command

The number "2" indicates a system call

The number "3" represents the C library function

The number "4" indicates a device or special file

The number "5" represents the file format and rules

The number "6" means games and other

The number "7" represents macros, packages, and other miscellaneous

The number "8" indicates system administrator-related commands

Options: Command options are available in two forms: Long option (-) and short option (-)

Long options: Use--boot, followed by complete words, such as--help

Short options: With-boot, followed by a single character, such as-a

Multiple short options can be combined, for example:-h-l-A = =-hla

However, long options can not be combined, such as--help can not be followed by another word.

Options can also have their own parameters, which can be called arguments, (note that between options and options, between options and parameters, there must be spaces between parameters and Parameters!) Also, the symbols used for the options and parameters of the command have the corresponding meanings:

1. The items in square brackets are optional;

2. Items that are not in square brackets or in curly braces are mandatory (there are also <>, but I have not seen them);

3. Black body (or bold)? ) words must be typed exactly as they are, which may be command names, flags, and literal characters;

4. Italics must be replaced with an appropriate value (the system that does not display italics is usually replaced with an underscore), as in the case of variables, it is necessary to add the appropriate values according to the circumstances;

5. Follow the ellipsis (...). ) parameters can be repeated multiple times;

6. If a separate option and a parameter are combined, then the option and parameter must be used simultaneously;

7. Two or more items separated by the | (vertical bar) character, indicating that you can select one from this list.

For example, [A|b] indicates that A and B can be selected or not, and {a|b} indicates that A and B must be selected.

To print the man manual, take mkdir as an example:

Man-t mkdir > Mkdir_man.ps

You can print PS directly and plan to send it to someone else and convert it to PDF:

Ps2pdf mkdir_man.ps Mkdir_man.pdf

The mkdir command is created recursively:

MKDIR-VP Scf/{lib/,bin/,doc/{info,product},logs/{info,product},service/deploy/{info,product}}

Output:

[Email protected] test]# MKDIR-VP Scf/{lib/,bin/,doc/{info,product},logs/{info,product},service/deploy/{info, Product}}
