In Linux the basic commands are written as:
command [ parameter Options ] [ file or path ]
The command to be used [ This is the one that needs to be variable but must be matched with the command used ] [ the file or path to be processed or consulted ]
1:makedirectorys Chinese meaning to create a directory, in the use of the command to reflect the way mkdir.
Example 1:mkdir/data This command means to create the data in the /(root directory) directory the directory.
Example 2:cd/;mkdir data The meaning of this command first use the CD command to jump to / (root directory) inside the command that uses mkdir to create data ( Note ' This semicolon is interesting in that it means separating the two commands within the same line .

mkdir The parameters of this command, query method with man mkdir this command query.

mkdir parameter Analysis and use example:
1:-m--mode=mode
Set file Mode ( as in chmod), not a=rwx-umask
-M This parameter's command parsing:m equals mode(pattern) meaning, internal meaning has changed umask default property usage is chmod.
Operation Case:

650) this.width=650 "width=" 408 "height=" "src="/e/u261/themes/default/images/spacer.gif "style=" Background:url ( "/e/u261/lang/zh-cn/images/localimage.png") no-repeat center;border:1px solid #ddd; "alt=" Spacer.gif "/>however, after using the- m parameter , the parameters after the creation of the data directory arerwx-r-x---(r=4,w=2,x=1,) where R stands for readable,w stands for writable,x Represents an executable, with a number representing 4,2,1.
2:-P--parents
No error if existing, make parent directoies as needed.
-P equals parents(dual) You can create multiple subdirectories consecutively in a directory that you create, such as recursive creation .
Case:
First create a directory data

If you want to create this, you need to add the parameter - p after mkdir . 650) this.width=650, "width=", "height=", "src="/e/u261/themes/default/images/spacer.gif "style=" Background:url ( "/e/u261/themes/default/images/word.gif") no-repeat center;border:1px solid #ddd; "alt=" Spacer.gif "/>
650) this.width=650; "width=" 310 "height=" "src="/e/u261/themes/default/images/spacer.gif "style=" Background:url ("/e/u261/lang/zh-cn/images/localimage.png") no-repeat center;border:1px solid #ddd; "alt=" Spacer.gif "/>

After adding- p This parameter has been successfully created, plus - p can create more than one such subdirectory. So - p This parameter is exactly the parameter of the recursive creation directory .
3:-v--verbos(verbose)
Print a message for each created directory
Print a message for each directory you create
Case:
650) this.width=650, "width=", "height=", "src="/e/u261/themes/default/images/spacer.gif, "style=" Background:url ("/e/u261/themes/default/images/word.gif") no-repeat center;border:1px solid #ddd; "alt=" spacer.gif "/ > Print Create information, I do not understand the use of this parameter, but I think it should be a combination with- p parameters.
