问题 Is there any difference between commands iisreset and iisreset /stop followed by iisreset /start ? 回答1: Take IISReset as a suite of commands that helps you manage IIS start / stop etc. Which means you need to specify option ( /switch ) what you want to do to carry any operation.

I don't know the string I am searching for in advance, and I would like to substitute in that variable. When I run this with the string directly specified (e.g "

问题 I have a piece of code that is meant to send the following to the linux command line: wc -l C:/inputdirectory/P* However, I need to run this script in Windows, and am trying to find the equivalent command. I have tried find /c /v C:/inputdirectory/P* But this throws an error, that /v is not a valid command.
