Re: New Feature Request

[felix]

I agree: python seem to be more apropriated language for complex operation.

Anyway, bash already offer a lot of features (like `coproc` and `read -t 0`)
usefull for IPC.

I wrote a little ``multiping`` bash script, as multithread demo, running many
parallels ping, reading all outputs and merging them in one line.

Sample: (Hitting `q` after ~4 seconds)

    $ multiping.sh www.google.com www.archlinux.org www.f-hauri.ch
