Using the FTP batch script under Windows

Interactive command under FTP

In general, we use FTP to a machine to upload files, download the operation,

In the command mode, it is basically:

1.FTP Host Name

2. Enter the user name

3. Enter your password

4. Toggle mode (ASC or bin)

5. Upload or download (Put or get)

6. Exit (bye or quit)

If you use some FTP tools, it's easier to operate.

FTP Batch processing script

If we want to automatically do some FTP action on a regular basis, we can write a batch file and put it on the windows task to execute periodically.

The general solution to this idea is: write two batch files, one is the main batch processing, used to invoke FTP; The other is a batch of FTP operations (the suffix of this file can be arbitrary).

Here is an example of two files: Main.bat; Ftptmp.bat

Main.bat's content is simple:

Ftp-n-S: "Ftptmp.bat"

The contents of Ftptmp.bat are as follows:

Open $ftphostuser $username $PASSWORDCD $filepathget $filenamebyeexit

The variables in the command should be replaced by themselves.

script with Parameters

Variables like the ones above may not be determined from the beginning, and this part needs to be passed in a dynamic way through variables.

Think about it, when the Windows. Bat script executes, you can add some parameters directly to the script and get it through%0%,%1%.

For example, when executing main.bat above, if you enter at the command line:

In the Main.bat script file

%0% corresponds to Main.bat.

%1% corresponds to 111.

......

See Example:

@echo Offecho%0%>>main.logecho%1%>>main.logftp-n-S: "Ftptmp.bat"

Now the problem is: Ftptmp.bat This file in the FTP script is not able to get the bat set of variables.

So, think of a solution to the idea can be: using Main.bat temporarily generated ftptmp.bat this file (variable replaced by the value passed in)

File similar to:

@echo Offecho Open%1%>>>ftptmp.batecho user%2%%3%>>ftptmp.batecho cd%4%>>ftptmp.batecho get%5% >>ftptmp.batecho Bye>>ftptmp.batecho exit>>ftptmp.batftp-n-s:ftptmp.bat

When called:

Main.bat host username password filepath filename

Reference

FTP [-v] [-d] [-i] [-n] [-G] [-s:filename] [-a] [-w:windowsize] [-a] [Host]

Parameters:

-V: Disables the display of remote server responses.

-D: Enables debugging, displaying all FTP commands that are passed between the client and the server.

-I: Turn off interactive prompts when multiple file transfers.

-N: Disables automatic logon to the initial connection.

-G: Disables the file name group, which allows wildcard character (* and?) to be used in local files and path names.

-s:filename: Specifies the text file that contains the FTP command, which will run automatically when FTP is started. No spaces are allowed in this parameter. Use this switch instead of redirection (>).

-A: Use any local interface when bundling data connections.

-w:windowsize: Overrides the default size of 4096 for the transfer buffer.

-A: Anonymous login.

Host: Specify the computer name or IP address to connect to the remote computer. If specified, the computer must be the last parameter.

Introduction to Simple Batch internal commands

1.echo command
Turn on echo or turn off the request Echo feature, or display a message. If there are no parameters, the echo command displays the current echo setting.
Grammar
echo [{On|off}] [message]
Sample: @echo Off/echo Hello World
In practical applications we will combine this command with a redirect symbol (also known as a pipe symbol, commonly used with > >> ^) to enter some commands into a file of a particular format. This will be reflected in a later example.

[Email protected] command
Indicates that the command after the @ is not displayed, and in the intrusion process (for example, using batches to format the enemy's hard disk), it is not natural to let the other party see the command you are using.
Sample: @echo off
@echo now initializing the program,please wait a minite ...
@format X:/q/u/autoset (Format This command is not allowed to use/y This parameter, it is gratifying that Microsoft left a autoset This parameter to us, the effect and/y is the same. )

3.goto command
Specifies to jump to the label, and when the label is found, the program processes the command starting from the next line.
Syntax: Goto label (label is a parameter that specifies the line in the batch program to which you want to turn.) ）
Sample:
if {%1}=={} goto noparms
if {%2}=={} goto noparms (if,% 1,%2 if you do not understand it, skip it first and there will be a detailed explanation later.) ）
@Rem check parameters if NULL show usage
: noparms
echo Usage:monitor.bat ServerIP portnumber
Goto END
The name of the tag can be random, but it is better to have a meaningful letter, the letter is added: to indicate that the letter is a label, the Goto command is based on this: to find the next jump to go there. It's better to have some instructions so that you can look at your intentions.

4.Rem command
Note Command, in C language equivalent to/*--------* *, it will not be executed, just a comment on the role, easy for others to read and your own later modification.
Rem Message
Sample: @Rem here is the descr1ption.

5.Pause command
When you run the Pause command, the following message is displayed:
Press any key to continue ...
Sample:
@echo off
: Begin
Copy a:*.* D:back
Echo, put a new disk into driver a
Pause
Goto BEGIN
In this example, all the files on the disk in drive A are copied to D:back. The comment that appears prompts you to put another disk in drive A, and the pause command suspends the program so that you can replace the disk, and then press my táng sash godless?

6.Call command
Another batch program is called from one batch program, and the parent batch program is not terminated. The call command accepts the label that is used as the calling target. If you use call outside of a script or batch file, it will not work at the command line.
Grammar
Call [Drive:][path] FileName [Batchparameters] [: Label [arguments]
Parameters
[Drive:} [Path] FileName
Specifies the location and name of the batch program to invoke. The filename parameter must have a. bat or. cmd extension.

7.start command
Calling an external program, all DOS commands and command-line programs can be called by the start command.
Common parameters of intrusion:
Min Start window minimized
Separate start 16-bit Windows programs in separate spaces
High starts the application in the high priority category
REALTIME starting the application in the REALTIME priority category
Wait to start the application and wait for it to end
Parameters these parameters for transmission to the command/program
The application that executes is a 32-bit GUI application when CMD. EXE returns a command prompt without waiting for the application to terminate. If executed within a command script, the new behavior does not occur.
