问题 I am looking for a way of deleting files that are contained in a folder with a specific name and then delete that folder afterwards. I know there there is the forfiles command line that I can use to delete the files, I just don't know how to get the folder name into the path. The folder is named based on the date that it was created and I want to delete the folder that is 7 days old. The folder is formatted as yyyymmdd. basically I need forfiles /P "C:\backups\[DATE 7 DAYS AGO IN yyyymmdd

问题 The forfiles command establishes several variables, indicated by a leading @ , which return data concerning the currently iterated item to the loop body. All the variables related to the path and name of the iterated item return the value enclosed in "" . Those are: @file , @fname , @ext , @path and @relpath . So: how can you get rid of the enclosing double-quotes? For example, the following code returns relative paths to text files in the given root directory: forfiles /P "C:\root" /M "*.txt

问题 I have a batch file to compress PNG files. When I drag and drop some files on batch, it starts to process all of them in the same time. And it becomes useless when I tried with hundreds of files (sure) The main part is something like that (simplified) START "" /W truepng.exe /out "%~n1_out1.png" %1 START "" /W pngwolf.exe --in="%~n1_out1.png" --out="%~n1_out2.png" I think I must to solve the "%1" part.

问题 I am trying to automate (on a Win7 system) an R script to read data from Bloomberg and write it to file, for processing by another system. My code runs in the R gui perfectly. So I wrote a batch file to call this .r file and output results to script.out as shown below. When I double click the batch file everything runs successfully. When I schedule a task to run the batch file, the R code runs, collects data from Bloomberg, but the write to file fails every time. R code library(quantmod)

问题 I have a massive number of files in one directory that I need to validate. The problem was, the file explorer takes too much time to load the file list and my whole computer becomes slow. So I wrote the following code to group files by moving certain number of files(shown as %limit% and will be 700) to numbered folders(shown as %DirN% ) for /f "tokens=1-2 delims=:" %%a in ('dir /b /a-d ^|findstr /n /v ".bat .cmd .txt"') do if %%a lss %limit% robocopy "%cd%" "%cd%\%DirN%" "%%b" /mov >nul This

问题 I'm trying to use iExpress to install dependencies on a small script that I've created on NodeJS. The iExpress package simply installs the packages Node: msiexec /i node.msi Then runs a Post installation Batch to put the Javascript into a folder in the %UserProfile% folder.

问题 My question, is extremely similar to the following SO question: How to get Java Version from batch script? In fact, it did almost solve my problem. The only difference is that I've to check the Java version based on %JAVA_HOME%, which the user is free to modify.
