I don't know if it is better to discuss it in jail@ or stable@ list
so a
do cross-post.
FreeBSD has many jail aware utilities but they are inconsistent in
taking JID as parameter.
For example "sockstat" takes -j JID "Show only sockets belonging to
the
specified jail ID" and it means numeric ID only.
On the other hand "ps" takes -J JID "This may be either the jid or
name
of the jail. Use -J 0 to display only host processes."
The same apply for "top", it understands jid as a number or name of
the
jail too.
Then again "cpuset" takes only numerical ID of the jail...
Shouldn't it be consistent across all FreeBSD base utilities so all
of
them can use numerical ID and name?
Good idea! Are you offering to create a patch? ;-)
It'd be my guess that given they weren't all created at the same
time,
nor
the same individual; that (quite probably?) the "jail" additions
were
also
added at different times, and by different people. So I'd imagine
that
unless someone with a commit bit decides one day they'd like to take
that
on. Someone(tm) maybe you? will need to propose a patch. :-)
If I can understand C sources I will create the patch by myself
instead of just posting here. Unfortunately I am able to code in sh,
php and a bit of javascript and perl but no C. :)

Sure, a PR would be handy for this - it's a pretty simple thing to
add, and
consistency would indeed be a good move.
Agreed. I'll review and commit such patches. I'd like to see a single
function for taking a "id or name". Ideally it would live in a
library, perhaps libjail?
It already lives there: jail_getid(3)
