Copy Code code as follows:
@echo off
Set Work_path=d:\test
D:
CD%work_path%
FOR/R%%s in (., *) Do (
Echo%%s
)
Pause
Results
D:\test\.
D:\test\A Folder 1\.
D:\test\A Folder 1\a File 1.txt
D:\test\A Folder 1\a File 2.txt
D:\test\A Folder 1\a File 3.txt
D:\test\B Folder 2\.
D:\test\B Folder 2\b File 1.txt
D:\test\B Folder 2\b File 2.txt
D:\test\B Folder 2\b File 3.txt
D:\test\B folder 2\b folder 3\.
D:\test\B Folder 2\b folder 3\b sub file 1.txt
D:\test\B Folder 2\b folder 3\b sub file 2.txt
D:\test\B Folder 2\b folder 3\b sub file 3.txt
Copy Code code as follows:
@echo off
Set Work_path=d:\test
D:
CD%work_path%
FOR/R%%s in (.) Do (
Echo%%s
)
Pause
Results
D:\test\.
D:\test\A Folder 1\.
D:\test\A Folder 1\a File 1.txt
D:\test\A Folder 1\a File 2.txt
D:\test\A Folder 1\a File 3.txt
D:\test\B Folder 2\.
D:\test\B Folder 2\b File 1.txt
D:\test\B Folder 2\b File 2.txt
D:\test\B Folder 2\b File 3.txt
D:\test\B folder 2\b folder 3\.
D:\test\B Folder 2\b folder 3\b sub file 1.txt
D:\test\B Folder 2\b folder 3\b sub file 2.txt
D:\test\B Folder 2\b folder 3\b sub file 3.txt
So
Copy Code code as follows:
FOR/R%%s in (., *) Do (
Echo%%s
)
And
Copy Code code as follows:
FOR/R%%s in (.) Do (
Echo%%s
)
What is the difference?
In the case of CD%work_path%, the results of these two commands are the same, as we have shown above. But
FOR/R%%s in (., *) Do (
Echo%%s
)
Does not have a CD%work_path% in the batch, it will display the traversal results under the folder where the batch file resides.
Copy Code code as follows:
@echo off
FOR/R "D:\test"%%s in (.) Do (
Echo%%s
)
Pause
Results
D:\test\.
D:\test\A Folder 1\.
D:\test\B Folder 2\.
D:\test\B folder 2\b folder 3\.
Copy Code code as follows:
@echo off
FOR/R "D:\test"%%s in (., *) Do (
Echo%%s
)
Pause
Results
D:\test\.
D:\test\A Folder 1\.
D:\test\A Folder 1\a File 1.txt
D:\test\A Folder 1\a File 2.txt
D:\test\A Folder 1\a File 3.txt
D:\test\B Folder 2\.
D:\test\B Folder 2\b File 1.txt
D:\test\B Folder 2\b File 2.txt
D:\test\B Folder 2\b File 3.txt
D:\test\B folder 2\b folder 3\.
D:\test\B Folder 2\b folder 3\b sub file 1.txt
D:\test\B Folder 2\b folder 3\b sub file 2.txt
D:\test\B Folder 2\b folder 3\b sub file 3.txt
It's a different thing to see.

Visit.bat-File Traversal batch Program
Copy Code code as follows:

:: Would sort-10/17/2004-v2
::
:: Program use:
:: Perform the specified action on the specified set of files/directory set/File list
::
:: Command-line Description:
:: 1. VISIT file set/catalog set [parameters]
:: Performing a specified operation on a set of files/directories
:: 2. VISIT @ file List
:: Performs a specified action on a file in the specified file list
::
:: Attention Matters:
::-A file Set/directory set can contain valid paths and wildcard characters
::-Path defaults to current path, file set defaults to *.* (not all files)
::-File Set/catalog set with double quotation marks when containing spaces
::-[parameters] supported dir switch:/s/a/o/l etc not with/b conflict
::-[parameters] not supported dir switch:/w/p/V etc with/b conflict person
::-[operations] written in Visitcmd.bat by the caller
::-[actions] Use the%visitfile% reference to traverse the file
::-Program checks to see if the file list exists, but does not check whether it is valid
::-Do not traverse directories and files in hidden/system directories (exceptions specified on the command line)
::
:: Usage Examples:
:: Visit C:\/ad/s traverse all directories in C disk, including subdirectories
:: Visit "C:\My document"/a-d Traverse all Files under "C:\My document"
:: Visit c:\*.zip/a/s traverse C-disk all. zip compression packs, including subdirectories
:: If you want to traverse multiple file/directory sets, you can use the DIR file set/a/s>> file list multiple times
:: Generate a complete list of files, then use the file list for traversal; or use Visitce.bat
:: When traversing a hidden/system directory that is not explicitly specified, you can use the attrib file set/s to generate
:: A list of files, and then refer to the%visitfile% third to last string in Visitcmd.bat code.
:: Re-use the file list for traversal
::
:: Test Report:
:: The limited black-box test is passed on the Win98 command line
:: Performance is still the biggest bottleneck

There's a similar problem under 2000SP4, the second problem is actually the incompatibility of FC, which, when displayed by line number, has 8 byte bits before each line of text, instead of the 9 under DOS6 and Win9x, so it's easy to solve, and the E-M ' Set file= ' in the debug script "Set fil=" can be changed to E.
But that's just the thing, the above mentioned three batches, but my training in DOS under the test prototype, done very rough, since the formal steering Win98 this March, the use of a lot of new problems, such as the file name contains a space problem, System/hidden attribute directory problems In NT, it encounters the problem of Chinese filename, and because of the excessive text flow control in the loop body, the efficiency is severely low. In addition, three programs function and implementation is not much different, there is no need to split.
Above all, rewrite the above code becomes necessary. Merging code, remedying vulnerabilities, improving performance, writing documents, there is the so-called V2 version, which actually did not spend a lot of effort.
However, an accidental afternoon, sudden whim, why not the visit command line function to do an enhancement, such as supporting multiple paths, multiple filters (filter), multiple file list, the original want to just add a command line parameter analysis loop, but truly realized, but once again realized the complexity of the command line, if For nesting, flush directed output, determine the directory when the root directory and subdirectory of the different, for the filter of low energy replacement (Win9x/dos), a new problem crowds, endless, unexpectedly consumed me half of the workday, only reluctantly achieved a rough version, this is called the V2CE version , and I have not much confidence in the rigorous testing.
Now, looking back at my work, in fact that v2ce version is not much of the application value. Multiple paths and filters, it can be done by calling visit more than once, and in fact, we use only one path and filter in most cases, and multi-parameter control brings a drop in usability, users always have a certain psychological barrier to the program with many parameters, and my personal hobby of DOS compression software, From high to low, rar,zip,arj in turn, ease of use is the first quantity; In addition, the most important thing is that the Multi-parameter control led to a significant increase in code volume and complexity, which once let me into the if for the construction of the Ghost maze and do not know North and South West, the program's readability is getting worse, Debugging is also more and more difficult, at the same time the compatibility of pull more Chinmaso.
These are the costs of functional ascension, although this is a more extreme example, but the balance between function and simplicity is evident in the importance of programming. Affinity of the interface does not mean that the affinity of the code, human needs do not mean that the human implementation, blindly to pass on the complexity of the user side to the designer (such as Windows), is not a very clever idea, and vice versa (such as Linux), This does not take into account the double pressure on the designer and the consumer by the increased code functionality.
