问题 I know that I can call !ls to issue ls command to shell. But I want features like history or tab-completion. Is it possible to do so in Google Colab? 回答1: You can use jQuery Terminal Emulator backed with google.colab.kernel.invokeFunction Here's an example notebook. The key part is here, where you back it with shell function. def shell(command): return JSON([getoutput(command)]) output.register_callback('shell', shell) And here's how you use invokeFunction : try { let res = await google.colab

问题 Is there any way of launching Oracle's Java.exe and have it take its command line options from a text file on Windows? What I'd like to be able to do is something like this: java.exe -optionsFile=myOptionsFile.txt MyClass where 'myOptionsFile.txt' contains a list of standard Java VM options such as "-classpath="my very long classpath" and "-Dthis=that" etc. All of the options must be present when Java.exe is run as it is the target of a memory debugging tool called VMMap. VMMap allows you to

问题 I am working in Windows platform. It is possible to open a PDF file at a specific page: AcroRd32.exe /A "page=3" "file.pdf" Is there a similar solution for printing a specific page?

问题 I often use the find command on Linux and macOS. I just discovered the command parallel , and I would like to combine it with find command if possible because find command takes a long time when we search a specific file into large directories. I have searched for this information but the results are not accurate enough. There appear to be a lot of possible syntaxes, but I can't tell which one is relevant. How do I combine the parallel command with the find command (or any other command) in

问题 I have a project which uses SPM (and does not use cocoapods). It compiles and runs fine. I can run SwiftLint autocorrect from the command line and that works too.

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.
