Right now, we are treating them as quoted newlines (here, the second echo is called with four arguments, 'b', $'\n', 'echo', and 'c'), rather than as command separators (three echos) or elided (the second echo would have just three arguments, 'b', 'echo', 'c'): $ tools/virsh -c test:///default ' echo a; echo b \ echo c ' a b echo c I guess that can be a followup patch. > Fix the grammer in a nearby comment while at it. > > Signed-off-by: Eric Blake <ebl...@redhat.com> > --- > tools/virsh.pod | 4 ++-- > tools/virt-admin.pod | 4 ++-- > tools/vsh.c | 6 +++--- > 3 files changed, 7 insertions(+), 7 deletions(-) > -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
