Win batch processing command basic operation

There are also reasons for introducing batch commands because some DLLs need to be compiled and copied to the following when using Jenkins to process integration the Web layer, otherwise reflection cannot be performed. All right, cut to the chase.

The batch file is a text file that is unformatted. include one or more articles. The extension is . bat or cmd. At the command prompt, type the name of the batch file, or double-click the batch file, and the system calls Cmd.exe to run them one by one in the order in which the commands appear in the file .

The following is a brief introduction to basic syntax usage

1echo command

Turn on or turn off the request Echo feature to display the current settings

echo [{on|off}][message]sample: @echo off/echo Hello World

[email protected] command

indicates no display @ the following command

You can't let the other person see the command you're using.

Sample: @echo Off@echo nowinitializing The program,please wait a minite ...

3goto 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.) )

4.Rem Command

Comment 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 is the descr1ption.

5.Pause Command

Run Pause Command, the following message is displayed:

Press any key tocontinue ...

This command helps to display the desired results

Sample: @echo off:begincopya:*.* D:backecho put a newdisk into driver Apausegoto begin

in this example, the drive all files on the disk in A are copied to D:back.

6. If Command

if indicates that the criteria will be judged to be met, thereby determining the execution of different commands. There are three types of formats :

6.1,if " parameter " = = " string " command to execute

if the argument equals the specified string, the condition is set, run the command, or run the next sentence. ( note is two equals)

as if "%1" = = "A" format a:

If {%1}=={} gotonoparms

If {%2}=={} gotonoparms

6.2,if exist filename to execute command

If there is a specified file, then the condition is established, run the command, otherwise run the next sentence.

as if Existconfig.sys edit Config.sys

7 for command

command is a more complex command that is used primarily for parameters that loop through commands within a specified range

using in a batch file for command, specify the variable using the %%variable

the whole syntax is :

For{vaiable|%%variable}in (set) do command[commandlineoptions]

• %variable specifies a single-letter replaceable parameter.
• (SET) specifies one or a set of files. Wildcard characters can be used.
• Command Specifies the command to execute on each file.
• command-parameters specify parameters or command-line switches for specific commands.

The corresponding format can also be

  For parameters   Percent of variable name In (" file or wildcard character do ( " action " )  

These are the two variants of the writing, but the expression is the same meaning

Parameters for have a 4 a parameter /d/r/l/f , respectively .

• / D Table of Contents only
• / R Recursive
• / L iterated algebraic value range (lowercase l)
• / F Iterative File parsing

Let's get a recursive notation.

Search a directory for a copy of a file to another directory

Set Jbosspath=e:\jenkins_publish\examsystem_net\examsystem_service\binset Projwhich=examsystemset objectbll=% Jenkins_net%\%projwhich%\itoo. EXAM.BLL\OBJ\RELEASEFOR/R "%objectbll%"%%i in (Itoo*.dll) does (Echo is copying%%i to%jbosspath%copy/y "%%i"%jbosspath%<p >) </p>

Summary:

these are the Bat Basic script Learning and understanding, basic grammatical structure and command prompt, but also the most basic records of the current learning, a little to organize it.
