问题 The Ruby Devkit is a 7-zip based self-extracting archive. I would like to invoke it silently without having to install 7-Zip to extract the files to a folder of my choosing, so that I can script the installation. I imagine it to be something like: cmd> DevKit-tdm-32-4.5.2-20111229-1559-sfx.exe /silent /dir="C:\DevKit" But that, of course, doesn't work. What command line flags must I use to silently extract this archive into a folder of my choice? 回答1: try this: C:\> DevKit-tdm-32-4.5.2

问题 In an NPM project, I'd like to have a commit for each build version. This will allow me to go back to the current build version, fix a bug, without having to go through all the QA of a new version. We can commit using npm scripts like this (see this answer): package.json "scripts": { "git": "git add . && git commit -m", } Then invoke the script by running: npm run git -- "Message of the commit" I'd like to automate it to run after npm run build. For this purpose we can create a new command.

问题 How can I get the current width of the windows console in an environment variable within a batch file? 回答1: I like the approach using the built-in mode command in Windows. Try the following batch-file: @echo off for /F "usebackq tokens=2* delims=: " %%W in (`mode con ^| findstr Columns`) do set CONSOLE_WIDTH=%%W echo Console is %CONSOLE_WIDTH% characters wide Note that this will return the size of the console buffer, and not the size of the window (which is scrollable).

问题 I am running an .exe file in the command line from a Ruby script that asks the user for a Yes/No response. I would like to know how the user can interact with it in Windows environment. I have tried all the possible options: system , backticks, %x() , Open3, Open4... and none of them work.

Any other idea? 回答1: Seems this is working under Windows too pipe = IO
