It makes running command line utilities from swift pretty easy. Chaining outputs from previous commands into subsequent commands is also rather simple. It’s based on Process but gives a lot of sugar that may be useful for you. I’ve been using it in one of my projects on an Ubuntu machine and it is easy to work with.<div class=""><br class=""></div><div class=""><a href="https://github.com/kareman/SwiftShell" class="">https://github.com/kareman/SwiftShell</a> <br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Nov 30, 2017, at 1:43 AM, Nick Keets via swift-corelibs-dev <<a href="mailto:swift-corelibs-dev@swift.org" class="">swift-corelibs-dev@swift.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class="">In that case I think the discussion is kind of moot, scripts are fundamentally different than apps, being terse is important and almost always you want to block.</div><div class=""><br class=""></div><div class="">If better scripting support is a non-goal for Foundation then `Process` is mostly fine as it is.

Swift scripts don't typically invoke `RunLoop.run()` or `dispatch_main()`, and without changing the way they generate main() functions to intrinsically do so (and then schedule main.swift's body on the main runloop/queue), I don't see a good way for it to do so. So an async API would be inconvenient to use from a Swift script.</div><br class=""><div class="">
