command-line-arguments

问题 My Requirement: For now when I run my python application with this command python main.py -d listhere/users.txt The program will run and save the result file as predefined name say reports.txt Now I want to add this functionality to allow users to choose what to put the filename and where to save as so python main.py -d -o output/newfilname -i listhere/users.txt Everything is same but I want another argument -o to be passed which will determine the filpath and name to be saved. How do I do it

问题 I've been reading a bit about how programs handle command line parameters. But the information seems to be "incomplete", things I've read: Options may have a preceding '-' or '/' sign if front of them. Options can have additional arguments (which go without a - sign) the option arguments follow the option directly, with or without a space. Options can be a single letter or a full word. optionscan be merged inside a single "option": -abc equals -a -b -c (Source) Now I'm really wondering: What

问题 Here is some example code I have right now to launch an app: Set objShell = Wscript.CreateObject("WScript.Shell") objShell.Run """C:\Program Files\Handbrake\HandBrakeCLI.exe""" I tried the following to launch the app minimized but it didn't work. I'm assuming this only works from a normal command prompt? Set objShell = Wscript.CreateObject("WScript.Shell") objShell.Run "start /MIN ""C:\Program Files\Handbrake\HandBrakeCLI.exe""" I've also tried launching a shortcut (which just gave a null

问题 I still know nothing on usage of such command-line options of MathKernel as -lmverbose -run cmd -password "pw" -pwfile "file" How are they working and what they are needed for? Are there other potentially useful command-line options of the MathKernel and the FrontEnd? P.S. Related answer. 回答1: Please consult the following reference pages: MathKernel and Mathematica. Opening "More Information" section you will see documented options. Its says -pwfile "file" ------- read passwords from file

问题 I'm trying to parse command-line arguments such that the three possibilities below are possible: script script file1 file2 file3 … script -p pattern Thus, the list of files is optional. If a -p pattern option is specified, then nothing else can be on the command line. Said in a "usage" format, it would probably look like this: script [-p pattern | file [file …]] I thought the way to do this with Python's argparse module would be like this: parser = argparse.ArgumentParser(prog=base) group =

问题 I think I'm doing something wrong or this isn't possible. I am able to run from the command prompt and create pdf fine using the paths in the code below. For more info the argument string when I use the command line looks like: chrome --headless --print-to-pdf="c:\Users\pwtph82\desktop\myreport\myreport.pdf" https://google.com Thanks for any help in advance. System.Diagnostics.Process process = new System.Diagnostics.Process(); process.StartInfo.WindowStyle = System.Diagnostics

问题 I run cmd (command line) and running my batch file from Java this way: final String cmd = "cmd /c C: && dir && cd C:\MyApp\Maxi && dir && C:\MayApp\Maxi\deploy.bat"; try { Process process = Runtime.getRuntime().exec(cmd); final InputStream in = process.getInputStream(); int ch; while((ch = in.read()) != -1) { System.out.print((char)ch); } } catch (IOException e) { System.out.println("IOException on CMD executing statement"); e.printStackTrace(); } It was working successfully, but I modified

问题 I'm trying to write an R script that takes in 3 arguments when run with Rscript: input file name, whether it has a header or not (values are 'header' or 'no_header', and a positive integer (the number of replacements; its for a bootstrap application). So, when I run it this way: Rscript bootstrapWithReplacement.R survival.csv header 50 it should, before running, check if: 1) The script indeed took in 3 parameters; 2) whether the first parameter is a file; 3) whether the second parameter has a

问题 I'm in a team that is converting a suite of Java applications to use OSGi. Previously, we used our own home-brew class loader system that has some similarities to OSGi, but it was nothing but trouble; we expect that by moving to using a system like Apache Felix we can have a system that works better while requiring less overall effort on our part to support. We have been converting the modules that make up the applications into OSGi bundles, a largely painless affair with the use of Spring DM
