(iv) TOKENS=X,Y,M-N extraction column
Format:
for/f "Tokens=x,y,m-n"%%i In (COMMAND1) do Command2
Usage:
Summary of the sentence: Extract the column.
Popular speaking, together to extract the contents of the section m of each line.
Therefore, you can use this command to specify the extraction of textual information.
Tokens= sometimes represents the extraction of all.
Tokens=m represents the extraction of column M.
Tokens=m,n represents the extraction of columns M and nth.
Tokens=m-n r
Example 1: Write a program that can receive an integer that prints half of the pyramid.
For ($i =0 $i
for ($t =0; $t
Echo ' * ';
}
echo '

?>
The effect of the following figure:
Example 2: Print a solid pyramid.
Analysis:
* ->1 layer, 2 spaces, 1 asterisks
* * * ->2 layer, 1 spaces, 3 asterisks
* * * * ->3 layer, 0 spaces, 5 asterisk
number of spaces = number of layers = maximum-$i
number of asterisks = ($i-1) *2+1
When creating a Web page form, if an option is required, usually an asterisk is added to the option, and the following is the way to share the required options for adding asterisks to your form using CSS.
When making a Web form, if an option is required, an asterisk is usually added to the option, such as Typecho's comment form:
Example:

Then add a little CSS style to the
The SIP protocol and some of its applications are worth learning. In this regard, we will explain the configuration of rtp sip today. SIP (Session Initiation Protocol) is usually used for VOIP calls, call establishment, call negotiation, and call termination. it helps two terminals to recognize each other, but it does not process media. When A call is established, it directly transmits media through real-time transmission protocol (RTP) between telephone A and telephone B.

Question:Enter a string of no more than 1000 characters, including numbers (1-9) and stars (*). The space in the string has been lost, so the connected numeric string can be regarded as many separate numbers or consecutive numbers, that is, spaces can be randomly added. There are two types of operations: 1) adding any types of characters (numbers or asterisks) at any position 2) exchanging any two characters in a stringThe minimum number of operations, so that the obtain

Forget it. If you cannot see it at a glance, put the strange code like yin yang aside. After sorting out the ideas, the entire "Yin and Yang puzzle" actually did the following:

To learn other people's works, you have a great advantage and can look at your own shortcomings.
Your own shortcomings are often due to lack of basic knowledge and poor basic skills.
Today, I want to add another lesson: asterisk expression (* expression ).
In the mine mining program, two asterisks are used. One is in Main. py, and the other is in game_scene.py.
First, let's look at the first situation:
@pyqtSlot()def on_action_Setup_triggered(self):
;
};
Struct E {
Char;
Int B;
Struct a C;
Double D;
};
For struct a, its own alignment value is 1 for char data, and for long data, its own alignment value is 4, the maximum alignment value of a struct is 4. The sequential steps of struct a in memory are as follows:(1) Char A. The address range is 0x0000 ~ 0x0000. The starting address is 0x0000, which must be 0 x 0000% 1 = 0. The member bytes are aligned.(2) Long B, the starting position of the address cannot start from 0x00001, bec
[ifaceaddr]Delete the specified IP address. inetaddr here represents the IP address. To delete an item in a table for the specified interface, use the ifaceaddr parameter. ifaceaddr here represents the IP address assigned to the interface. To delete all items, use the asterisk (*) wildcard to replace inetaddr.-S inetaddr etheraddr [ifaceaddr]Add a static entry that parses the IP address inetaddr into the physical address etheraddr to the ARP cache.

process#crontab-u username controls the cron table as a userThere is also an important point of knowledge, that is, when the user's scheduled task is established, it is stored in the/var/spool/cron directoryWhen you edit the cron table for the current user using CRONTAB-E, a VI file appears, and the cron format is like this. Divided into two columns, the left is the time, the right is the command to run. Time is made up of 5 parts.Cases:* * * * * * Wall Hello Everyone5 asterisks represent: Minu
An asterisk (*) character indicates that the regular expression preceding it can occur 0 or more times. That is, if it modifies a single character, the character can be there or not, and if it is there, it may not appear more than one. You can use the asterisk metacharacters to match the words that appear in quotation marks.-"*hypertext" * *Whether the word "hypertext" appears in quotation marks will be mat
