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. Can you please tell me why this isn't working? *note, the command itself doesn't say "inputdirectory", it has the correct directory, it's just too tedious and private to type out 回答1: How

问题 I'm trying to get the output of wmic process call create so I can get the ProcessId of the newly created process. If I just run: wmic process call create "notepad.exe a.txt","d:\" It works just fine (it opens the file a.txt under folder d:\ with notepad ). Now, if I try: for /f "usebackq delims==; tokens=1,2" %i in (`wmic process call create "notepad.exe a.txt","d:\"^|findstr ProcessId`) do @echo pid = %j It doesn't, and shows me the error: Formato incorrecto.

问题 [purpose] This simple command sequence runs expected in the Windows' CMD shell: dir & echo hello will list the files and directories and echo the string. However, the following command sequence does not run as expected (at least by me): C:\Users\Administrator>set name=value & echo %name% %name% C:\Users\Administrator>echo %name% value C:\Users\Administrator> As we can see, the first echo cannot get the environment. Could you help to comment? Any comment will be appreciated! PS: OS:Windows 7

问题 for /r %%i in (*) do (echo %%i) Results in %%i was unexpected at this time Why? 回答1: You must be trying to run the command from the command line and not from within a batch file. Use a single % instead of two when running from the command line. for /r %i in (*) do (echo %i) Type HELP FOR from the command line and read the 3rd paragraph. 回答2: Syntax: FOR /R [[drive:]path] %%parameter IN (set) DO command Need the path before %%i... which is why it's Unexpected If you want to do * for current

问题 I'm writing a Windows batch script. By default, the pause command will pause the script and display the text "Press any key to continue..." . How do I modify this text to display my own text to the user? Thanks. :) 回答1: You could hide the text from the pause command by using this: pause >nul Then you could echo your own message to tell the user it has paused: echo The batch file has paused So the full script might look like this: @echo off echo Hello World! echo The batch file has paused

问题 I want to prompt the user for some input detail, and then use it later as a command line argument. 回答1: You can use set with the /p argument: SET /P variable=[promptString] The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty. So, simply use something like set /p Input=Enter some text: Later you can use that variable as argument to a command: myCommand
