 | WebVM is a server-less virtual Linux environment running fully client-side |
 | in HTML5/WebAssembly.                                                      |

 | In this demo, it runs an unmodified Debian distribution including many     |
 | native development toolchains.                                             |

 | WebVM is powered by the CheerpX virtualization engine, and enables safe,   |
 | sandboxed client-side execution of x86 binaries on any browser.            |

 | CheerpX includes an x86-to-WebAssembly JIT compiler, a virtual block-based |

You know that it’s running linux, right? Seems like you still don’t even know how to use linux.

bluefoxy009 commented 2 years ago

Your trying to cat a directory, then you try to cd /b Bro that’s a Windows command

Your trying to cat a directory, then you try to cd /b Bro that’s a Windows command

Was seeing what it did with nonexistent directories. Also, linux doesn't dump garbage to the terminal when you try to read from a directory.
