Batch files are unformatted text files, and now diskless cleanup is mostly achieved because it's simple and practical to make it easier to create batch files.
Brief introduction to a simple batch process internal command

% Variable specifies a single letter replaceable parameter.
(SET) specifies one or more files. Wildcard characters can be used.
Command specifies the Command executed on each file.
Command-parameters specifies a parameter or command line switch for a specific command.
For example, a batch file contains one row:
For % C in (*. bat *. txt) do type % C

A lot of novice friends have encountered such a problem is how to batch process change file name? You may not find a rename command ren in Excel, use it to quickly complete the batch file name, there is a good tutorial, you can try to operate under.

:

C:> echo "this is a test""This is a test"
In the input a "This Is A canshu", a is the new. BAT file name A (. BAT can be written or not), and the "This Is A canshu" statement after a is a parameter, when the program is running, the parameter is automatically placed in the batch processing program. so where? Put it at % 1.

Syntax
Echo [{on off}] [Message]Sample: @ echo off/ECHO Hello World
In actual application, we will combine this command with the redirection symbol (also known as the pipeline symbol) to input some commands to a file in a specific format. this will be reflected in future examples.

The batch file can also use parameters (equivalent to the command line parameters of the doscommand) like C functions, which requires a parameter identifier "% ".% [1-9] indicates a parameter. A parameter is a string separated by spaces (or tabs) after the file na

Perl version of batch renaming, with Perl The advantage is that you can use regular expressions to complete the very peculiar function.The format of the parameters for the Perl version:Rename perlexpr filesNote that the Perl version of rename has only two parameters, the first parameter is a Perl regular expression, the second parameter is the file to be processedExample of a man rename help:
Examples are as follows: Batch create 10 random string of files, require each file name after adding _aaa, suffix name unchanged;[[email protected] goodboy]# lsadddbbdedf.html baacjaiija.html bhcfaabcfh.html dgjdcdfbca.html efejadfdji.htmlagdhcdeaje.html bgffbffjcg.html cbbiebdafh.html diadebbhag.html jcajafgejf.htmlScript 1:[email protected] ~]# cat 02.sh#!/bin/

XCOPY also has a number of functions that are added to the parameters to complete. The effect of the above/s/e parameters is the root directory and the empty directory are replicated in the past, some use examples and parameters are described as follows:1, such as simply copy E:\ All files on disk to D:\ On the disk, enter "xcopy E:\*.* D:/s/h" on the line
