cmd returns to the previous directory and enters the cd command. cmd is a command interpreter in Windows.

Commands used to execute the input. Most of these commands automate tasks through scripts and batch files, perform advanced management functions, and troubleshoot or resolve certain types of Windows issues.

What cmd does:

cmd can be used to create directories or files.

cmd can be used to delete directories or files.

cmd can be used to modify directories or files.

cmd can be used to view directories or files.

cmd can be used to open directories or files.

Command Shell is a stand-alone application that provides users with the ability to communicate directly with the operating system.

It provides a non-graphical runtime environment for character-based applications and tools that executes commands and echoes MS-DOS-style characters on the screen.

It provides the ability to parse command-line input, execute programs, process pipelines, and complete a certain programming language for the banquet chain, and is responsible for the parsing of batch files.

The Microsoft Windows system is based on the command interpreter on Windows, similar to Microsoft's DOS operating system.

Usage: "MS-DOS mode" under Windows CE and Windows NT platform-based operating systems (including Windows 2000 and XP, Vista, and Server 2003). The command prompt in the Chinese version of Windows XP further improves the compatibility with DOS operation commands, and users can directly enter Chinese call files in the command prompt.

Type "command" under 9x to open the command line. On the NT system, you can enter cmd to open, and after Windows2000, it is replaced by cmd, and the cmd command is used to query the information of the system or judge the quality of the network. <>

Some commands in the dos command about the directory:

dir – Column directory.

cd - changes the current directory.

md - Create a subdirectory.

copy - copy the file.

format - format the disk.

Extended information: dos commands.

Some of the single symbols:

In for means using enhanced variable extensions.

In %var:n,m% it means that the extended environment variable is used.

Specify the string for the location.

Represents the unary operator in set a.

Negate the operands bitwise.

In set a, the unary operator represents logical non. For example, set a a=!0, in which case a represents logical 1.

Hide the command line.

Echo of itself, often used in batch processing.

Middle. The findstr command indicates the end of a line.

In the prompt command, it means to escape (symbolize or effect) the characters that follow.

A binary operator in set a, which represents the arithmetic remainder.

In the command line environment, the for command in is followed by a character (which can be a letter, a number, or some specific characters) to specify a loop or traverse indicator variable.

In a batch, a number is followed to indicate the parameter specified when the batch is currently executed.

In other cases, % will be stripped (batched) or retained (command line).

Remove the escape function of specific characters, such as & |etc., but not including %. For example, if you want to display some special characters on the screen, such as > and other symbols, you can add a symbol in front of it to display the characters that follow it, that is, to display one, that is, to display a |characters;

A binary operator in set a, which represents bitwise XOR.

The specified character set is not matched in findstrr.

command to concatenate characters. For example, if I want to execute two commands at the same time on a single line of text, I can use & command to connect the two commands.

In set a it is bitwise with.

Representing any arbitrary character, that's what we usually call it"Wildcard.

For example, you want to be in the root directory of the C drive.

Find all the text files in the root directory of the C drive (.).txt), then you can enter the command"dir c:\*txt"。

A binary operator in set a, which represents arithmetic multiplication.

In findstr r it means that the previous character will be matched multiple times.

Range notators, such as date lookups, can be used in tokens operations in the for command.

Concatenating two characters in findstr r indicates a matching range.

Following the end of some commands indicates a switch that takes the opposite direction.

In Set A:

1.Indicates a negative number.
