Which file handle, the one from which gzip reads that has nothing to do with Perl? Well, you could pipe information to `gzip` from Perl, so you're back to using `open3` or the like. Additionally, you need to feed information to `gzip` while reading from `mycommand`, so you need some kind or parallisation. You could sockify the pipes and use `select` or you could use threads. It's getting complicated fast, and it might not even help enough, depending on how long it takes for `mycommmand` processes a pipe buffer's worth of data.	[reply] [d/l] [select]
