Some completers for libvirt related tools might want to list domain IDs only. Just like the one I've implemented for virt-viewer [1]. I've worked around it using some awk magic, but if it was possible to just 'virsh list --id' then I could drop awk.1: https://www.redhat.com/archives/virt-tools-list/2019-May/msg00014.html Signed-off-by: Michal Privoznik <mpriv...@redhat.com> --- Diff to v1: - Documented the new switch in the manpage - Allowed --id to be used with --all docs/manpages/virsh.rst | 21 +++++++++--------- tools/virsh-domain-monitor.c | 42 +++++++++++++++++++++++++----------- 2 files changed, 39 insertions(+), 24 deletions(-) diff --git a/docs/manpages/virsh.rst b/docs/manpages/virsh.rst index d34a1c8684..848e1a6458 100644 --- a/docs/manpages/virsh.rst +++ b/docs/manpages/virsh.rst @@ -621,7 +621,7 @@ list list [--inactive | --all] [--managed-save] [--title] - { [--table] | --name | --uuid } + { [--table] | --name | --uuid | --id } [--persistent] [--transient] [--with-managed-save] [--without-managed-save] [--autostart] [--no-autostart] @@ -758,16 +758,15 @@ If *--managed-save* is specified, then domains that have managed save state in the listing.

Didn't you want to add something like the following? If neither *--name* nor *--uuid* is specified, but *--id* is, then only active domains are listed, even with the *--all* parameter as otherwise the output would just contain bunch of lines with just *-1*. Otherwise the code is very unclear for no reason. If that is the case, then Reviewed-by: Martin Kletzander <mklet...@redhat.com>
