I think we can reasonably assume that the two most common shells are bash followed by zsh today. Neither of these have a "terminal freeze" by default from upstream, and so unless distro people add these lines to everyone's rc, the majority won't have a "terminal freeze" by default. I think this is also a safe assumption: Arch Linux (which I run) does not, and Debathena (MIT's Debian based setup) and thus likely Debian as well do not. Now in the absence of a terminal freeze (i.e a "default" shell config), try out Nicolas' old example (https://ffmpeg.org/pipermail/ffmpeg-devel/2015-July/176475.html): ffmpeg -lavfi testsrc -f framecrc - | head zsh is clobbered by this. bash needs a slight modification, i.e ffmpeg needs to run in a harness (https://ffmpeg.org/pipermail/ffmpeg-devel/2015-August/176560.html): strace ffmpeg -lavfi testsrc -f framecrc - | head bash and zsh are both clobbered by this. Both of these examples are with current git HEAD. > > > [...] > > -- > Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB > > DNS cache poisoning attacks, popular search engine, Google internet authority > dont be evil, please > > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > http://ffmpeg.org/mailman/listinfo/ffmpeg-devel > _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
