What commands are there in DOS?

First, the basic command

1 directory

No parameters: View files and folders in the current directory.

/s: View files and folders in the current directory and all its subdirectories.

/a: View all files, including hidden files.

/ah: Show only hidden files.

/w: Displays files and folders in a compact way (5 files in a row).

/p: Paged display (it will automatically pause after displaying one page).

|more: The symbol in front is the one above "\", which is called the redirection symbol, that is, putting a

The result of one command is output as a parameter of another command. More is also an order, dir /w |more.

The result is the same as that of dir /w /p p p.

You can use other parameters: dir/? View.

2 CDs

Cd directory name: Enter a specific directory. If you see a directory that says: abcdef ghi, just

Enter: cdabcdef.ghi to enter the directory.

Cd\ restore to the root directory.

Cadmium .. Return to the previous directory.

3 rd boulevard

Md Directory Name: Create a specific folder. (dos is used to calling directories, and win is used to calling text.

Clip. Ha ha! )

Rd directory name: delete a specific folder.

4 cls

Clear the screen.

5 copies

Copy Path \ File Name Path \ File Name: Copy the file to another place.

6 move

Move Path \ File Name Path \ File Name: Move (that is, cut+copy) a file to another file.

A place.

7 del

Delete file name: Delete a file.

Del *. *: Delete all files in the current folder.

Del could not delete the folder.

8 Deltry Street

Delete this folder and all its subfolders and files. That's great. . . Don't use it indiscriminately.

9 format

X:: x represents the drive letter and formats a partition. Use Fat file system format in dos.

Yes, you will be asked if you want to convert to ntfs when installing windows2000.

10 type

Type text file name: Displays the contents of the text file.

1 1 Edit

In fact, this is a small program for editing text files.

12

Any old file name and new file name: change the file name.

Second, the common commands about the network

1 flat

Ping host ip or name: send four Internet control message protocols to the target host to test whether the other host receives them.

To respond, it is generally used to test whether the ordinary network is unobstructed. But ping doesn't mean the network.

Unable to connect, the target host may have a firewall and prevent icmp response.

Ping -t: Continue sending packets. Of course, they are too small to be called attacks. Some people wrote it themselves.

Some programs similar to ping command are introduced, and large packets are sent continuously to block the target host.

Network connection.

2 net

The suggestion is to use net/? Get specific help information. There are really many parameters, and there are parameters below.

Count. Commonly used: net view \\ host to see * * * enjoy, net start/stop service to start and stop.

I don't like courier service very much.

3 netstat

Netstat host: View the current tcp/ip connection status of the host, such as port status.

4 National Bureau of Statistics

Nbtstat host: Check the NetBIOS name used by the host.

5 tracert

Tracert host: one by one, look at how far you have gone from yourself to your goal. For example:

Www.ncie.gov.cn then waited. . . You will see the part of the route you have passed.

Generally, larger routers, such as the backbone routes of telecommunications, are marked in English except ip.

Yes

6 pathping

Pathping host: Similar to tracert, but it can display some letters that tracert can't.

Rest. You can try it yourself.

7 ftp

Character ftp, I like to use; Cuteftp is not required.

8 Remote login

Character-based remote login program is a very popular remote login program for network personnel. I've been often recently.

Used to debug the mail server.

9 ipconfig is very useful for network configuration and debugging. . . Orders.

Displays the network interface status of the current machine without parameters.

/Everything starts with the details.

/release releases the current ip.

/renew reapply for ip.

/flushdns refreshes the dns cache.

/registerdns retransport and register yourself on the dns server.

. . . . . .

10 arp operation current arp cache.

-a shows the arp cache.

-d Delete the cache record.

-s Tian Jia has a cache record.

1 1 nslookup is a powerful tool to eliminate dns errors. Is an interactive tool. Please try to understand the function and working principle of dns before using it.

Xcopy is an external command, that is to say, it is a small program, sometimes it can't be found on floppy disk or hard disk. . . Pass out. . . Of course, courage is better than plagiarism. I like to add the /e parameter.

Smartdrv.exe loads the disk cache, and the parameter is the cache size in kb.

For example, smartdrv 32768 will load a 32M cache.

The role of cache is very obvious when installing WIN2K! It takes about 3 hours to install WIN2K PRO without cache, and only 30 minutes after loading 8M cache.

The principle is to divide an area in the memory, and constantly read the data on the hard disk into that cache area during installation to make full use of the memory.

AT plays the same role as mission planning.

The following is how to use it. You can enter it at the command prompt: AT/? Ask for help.

The AT command schedules commands and programs to run at a specific date and time.

To use the AT command, the scheduling service must already be running.

In [\ \ computer name] [[id] [/DELETE] | /DELETE [/YES]]

At [\ \ computer name] time [/interactive]

\\computername specifies a remote computer. If this parameter is omitted, the command will be scheduled to run on the local computer.

\\ 127.0.0. 1 stands for this machine. It means the same as not adding this parameter.

Id an identification number assigned to a predetermined command.

Used to identify tasks. For example, to add several tasks, ID= 1 means the first one!

/delete the command to delete the plan. If the id is omitted,

All scheduled commands on the computer will be deleted.
