Hello, Whereas Perl’s `system` and `exec` built-ins can accept a list of parameters to pass to the called program, `readpipe` only takes a single argument. Thus, if you want to pass parameters to the called program, you have to apply shell quoting, which is error-prone. This is confusing and strange, I think. It would seem ideal for `readpipe` to work as `system` and `exec` do. Thoughts? cheers, -FelipeThread Next
