command-line

问题 Is there a way in python to print something in the command line above the last line printed? Or, similarly to what I want to achieve, remain the last line intact, that is, not overwrite it. The goal of this is to let the last line in the command line a status/precentage bar. Output example: File 1 processed (0.1% Completed) Next refresh: File 1 processed File 2 processed (0.2% Completed) Next refresh: File 1 processed File 2 processed File 3 processed (0.3% Completed) 回答1: from time import

问题 When using jq to process JSON, I often lose the overview due to long JSON objects. Thus, something like jq . | less would be nice. However, although the above works, the nice coloring by jq is gone. Is there another way to read jq 's output line by line, or window by window, without having the terminal spammed with the full JSON object? Edit: This did not work for me: echo '{"hello": "world"}' | jq . | less -C 回答1: Use the jq -C (colorize) option, with more -r or less -r . 回答2: report.json is

问题 Language: C# I have to pass a huge string array (built dynamically) as an argument to run an exe. I am thinking of acheiving it by the below 2 ways. But I am not feeling confident. I can create it as one string delimited by spaces. I can invoke the exe through Process.Start. Hence the running child process considers the space and holds as a string array. However I am unsure about the string array limitation. Suppose if my string array count exceeds more than 10,000 I can create it as one

问题 Despite a ton of Googling, I can't find any docs for pip's command line options/arguments. What does pip install -U mean? Does anyone have a link to a list of pip's options and arguments? 回答1: Type pip install -h to list help: -U, --upgrade Upgrade all packages to the newest available version So, if you already have a package installed, it will upgrade the package for you. Without the -U switch it'll tell you the package is already installed and exit. Each pip subcommand has its own help
