This can still lie, e.g. under setarch. $ setarch i386 uname -rm 4.9.6-200.fc25.x86_64 i686 It doesn't even matter that my /usr/bin/uname is a 64-bit binary. And while Fedora puts the arch in the release string, you can't rely on that everywhere. But I don't know any truly foolproof way. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Strace-devel mailing list Strace-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/strace-devel
