问题 How do I save the result of evaluating a mathematical expression to a variable using bash? My code is the following: W1=$(bpimagelist -U -d 11/01/2013 00:00:00 -e 11/05/2013 00:00:00 -pt FlashBackup-Windows | tail -n +3 | awk '{s+=$5} END {print s/1024/1024/1024}') W2=$(bpimagelist -U -d 11/01/2013 00:00:00 -e 11/05/2013 00:00:00 -pt MS-Windows | tail -n +3 | awk '{s+=$5} END {print s/1024/1024/1024}') echo "$W1+$W2" | bc | awk '{printf "%.02f\n", $1}' Console Output: 96.86 I am looking for a

问题 I need to create a simple password program where the program asks user to input password and when user inputs, it shows the characters as asterisks. Every tutorial out there uses getch() (in conio.h ). But I don't want to use it. Is there any easy alternative for doing so? I'm using Windows 10. P.S: Please don't confuse this to be a duplicate of this question: Alternative function in iostream.h for getch() of conio.h? Because that question asks for holding screen output whereas I need to mask

问题 This question already has answers here : Why does my string not match when reading user input from stdin? (3 answers) Closed 1 year ago . I am currently working on a simple "user input" program. The user can enter a number, which I get with std::io::stdin().read_line(&mut let_name_here).ok().expect("Error"); . After getting the user input I want to print it to the console for a review. I have noticed strange behavior within the println! macro. The following code println!("Your input: {}", let

问题 Here's what I'm trying to do: I have a class called RandomRoomGenerator, which has a method called GenerateRoom. This GenerateRoom method is called inside my main method based on the grid size(the width or height) multiplied by itself to get the total number of rooms. The method itself creates a new room with parameters chosen randomly from my ItemDB and RandomRoomValues. The problem is, I need a way to generate the room's position without it overlapping previously generated rooms. So far I

问题 I'm trying to figure out how to close an Excel instance properly if the Python console program is interrupted and closed while executing. Below is a minimal reproducible example: # import pythoncom import traceback import win32com.client import win32api def exit_handler(arg): file = open('Log.txt', 'w') file.write(f'{repr(workbook)}\n{repr(excel_application)}\n') try: # pythoncom.CoInitialize() workbook.Close(SaveChanges=False) excel_application.Quit() except Exception: file.write(traceback

问题 When my console app first runs, I execute Console.Title = "whatever" to change the window's title. What bugs me is that there is that split second where the console window's title is the path to the EXE itself. I'd like to think that there's a way to set the title so that it's stored in the application settings itself so that I don't have to set it with code. 回答1: Perhaps run it as with a batch file called "my_console_app.bat"? start "My display name" my_console_app.exe 来源： https:/

问题 I want to read user inputs from a C# console application targeting .NET Core 3.1. In some situations, the user shall have the choice to cancel the input and the related operation by pressing the Escape key at any point of time when the user is prompted for input. The following script works for empty strings (user just hit Enter and nothing else), and normal user input (user enters characters and confirms with Enter ). But there is a issue: When the user cancels the input (hits Escape ), the

问题 .NET Core 2.2 I have a basic CLI created with dotnet new console . It uses HttpClient to make web requests. How can I see trace or logging information about these requests?
