Also is there a way to have it do exactly what it does without displaying every step in the loop in the command prompt window.

问题 There is a file named doctitle.txt which contains the title. I want to use this title to rename another file, currently name file.pdf, so I did: for /f "delims=" %%x in (doctitle.txt) do set "DOCTITLE=%%x" move file.pdf %DOCTITLE%.pdf This works fine, if there no space in the title string, i.e "DocumentTitle". But fails if there is a space in the title, i.e "Document Title". What could be done to overcome this issue? 回答1: Try: for /f "tokens=*" %%x in (doctitle.txt) do set DOCTITLE=%%~x move

问题 We have several hundred clients with unique server names on their own local networks that hosts a specific folder called "Installs". Ultimately what I'm trying to put together is a batch that finds this folder with said name and use an MSI file in that folder to install on their machine. The server name could just be anything, the only thing I know for sure is that it will be sharing out that specific folder. I've tried many variations of net view, find, dir, wmic share.. no such luck, no

问题 I'm running Node.js project as service using nssm.
