command-line

问题 I have some questions on the subject, of commas compared to space, in delimiting parameters. They are questions that C programmers familiar with the cmd prompt, may be able to throw some light on.. I know that when doing c:\>program a b c there are 4 parameters [0]=program [1]=a [2]=b [3]=c According to hh ntcmds.chm concepts.. Shell overview ; and , are used to separate parameters ; or , command1 parameter1;parameter2 Use to separate command parameters. I see dir a,b gives the same result as

问题 I want to be able to take a command string, for example: some/script --option="Quoted Option" -d --another-option 'Quoted Argument' And parse it into something that I can send to child_process.spawn : spawn("some/script", ["--option=\"Quoted Option\"", "-d", "--another-option", "Quoted Argument"]) All of the parsing libraries I've found (e.g. minimist, etc.) do too much here by parsing it into some kind of options object, etc. I basically want the equivalent of whatever Node does to create

问题 I am calling java.lang.Runtime.exec(...) in my Java program to run a command (some FFMPEG commands) simply passed to my function: private static void RunCommand(String command) throws InterruptedException { try { // Execute command Process proc = Runtime.getRuntime().exec(command); } } It runs OK for simple FFMPEG cases such as ffmpeg -i input.avi -c copy output.avi . But for one of the commands, apparently it doesn't run. When I copy/paste the exact String in command line, I am able to run

问题 I created a runsettings file which looks like this <?xml version="1.0" encoding="utf-8"?> <RunSettings> <TestRunParameters> <Parameter name ="environment" value="PROD" /> </TestRunParameters> </RunSettings> And then in my TestSetup portion (using LeanFT for UI tests) I specify that the target environment is contained under a paramater called environment string env= TestContext.Parameters["environment"]; This doesnt seem to work, and I am not getting any particular error messages. Is this the

问题 I have written some image acquisition software and as I am acquiring these images I want to add the last image onto the end of a video file (a time-lapse of all images acquired so far). This will give a video view of all the images. However I am struggling with trying to add the single frame. I have generated the time-lapse fine. The way I am doing this is waiting until I have gathered 10 images, then I generate the time-lapse. The command I have used to generate the time-lapse I will be

问题 I am complete new in writting powershell scripts. So far I was using plain batch for my purpose as this is the requirement by my company. Inside this batch I am using nested foor loops to make a comparison of two .txt files, in detail I wantdo do the following: File 1 contains lots of strings. Each string is in one seperate line with a preceded number and semicolon like so: 658;RMS File 2 is some long text. The aim is to count the amount of occurences of each string from File 1 in File 2, e.g
