Issue #7025 has been reported by rogerdpack (Roger Pack). ---------------------------------------- Feature #7025: way to wait for closing with IO.popen object https://bugs.ruby-lang.org/issues/7025 Author: rogerdpack (Roger Pack) Status: Open Priority: Normal Assignee: Category: Target version: Hello. I noticed that it seems, if you do: IO.popen("something", "w") there's currently no way (without using a block form? [1]) to tell that this process has exited (or do correct me if I'm wrong). So consider this a feature request for such. Thanks! -roger- [1] http://stackoverflow.com/questions/1217351/io-popen-how-to-wait-for-process-to-finish -- http://bugs.ruby-lang.org/
