问题 I need help returning the file name of a file located in a folder. I have read other questions asked a few times and the answer seems to be: for /d %F in (*.*) do echo %~nxF Although this seems to work for everyone else, when I run this within a batch file it has an exception and states that '~nxF' is not expected at this time.

问题 I need netcat to listen on incomming HTTP requests, and depending on the request, I need to run a script. So far I have this; netcat -lk 12345 | grep "Keep-Alive" So every time netcat recieves a package that contains a "keep-alive", I need to fire a script. It needs to run in the crontab...

问题 i have this error in building in atmel studio 6 : C:\Program Files\Atmel\Atmel Studio 6.1\shellUtils\make.exe all 'C:\Users\' is not recognized as an internal or external command, operable program or batch file. 回答1: The entire string you show needs to be in quotes.

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 8 years ago .

问题 I have been toying with the Process class in C#. I have some code below I'd like to use to open cmd.exe and run the DIR command. However, when I attempt to use the code, the cmd.exe opens, but no command is run. Why is this happening and how do I fix it?
