如何使用批处理脚本从“输出”文件夹中删除所有文件？

Question

I have a folder structure as below:

L:\MyProject\Extract\
                    Activity    Input
                                **output**
                                SSIS
                                Results
                                Headers
                    Account     Input
                                **output**
                                SSIS
                                Results
                                Headers
                    Balance     Input
                                **output**
                                SSIS
                                Results
                    .
                    .
                    .

Here, I need to find output folder and delete all files present inside each "output" folder. I am using following script:

SET FolderPath=%1

for /f "usebackq" %%a in (`"dir %FolderPath% /ad/b/s output"`) do SET Folder="%%a"
del %Folder%\*.* /Q

But using above script, I am able to delete files which are present in "%%a"(last path of output folder). How to do it recursively...? Or is there any array concept to store all paths where output folder is present?

Answer 1

I see three problems in your code.

First, the for loop does not find the output subdirs under FolderPath , but iterates over all the subdirs of FolderPath .

One way to solve this is to specify

for /f "usebackq" %%a in (`dir "%FolderPath%\output" /ad/b/s`) do 

Note that I have moved the quotes, just to prepare for the case of names with spaces, which was your second problem. You might further simplify it with

for /f "usebackq delims=" %%a in (`dir "%~1\output" /ad/b/s`) do 

note that delims avoids spaces work as delimiters and %~1 removes the quotes of the parameter

And finally, the for loop, in each iteration, just set s the Folder variable, it does not invoke the del command, that is placed outside the loop.

One easy way to solve this problem is to invoke the del command on %%a without setting the variable folder

for /f "usebackq delims=" %%a in (`dir "%~1\output" /ad/b/s`) do del %%a\* /q

You could use the find command to find all subdirectories of the current directory.

To list files in all directories named Output :

find . -name Output -type d|find -type f -exec ls {} \;

To delete all files in directories named Output :

find . -name Output -type d|find -type f -exec rm {} \;
