Re: amdump issues involving wildcards--quoted wildcards appear to be sent to, and thus being interpreted literally by, gtar

My conjecture of what's happening is that the gtar command is being
run with quotes around the items in the "include" statement in my

Have a look in /tmp/amanda/sendbackup.xxx.debug. That should show you
what the command line arguments being used look like.

Sorry for taking so long to reply since things've been pretty hectic
around here.
Anyway, what originally started this was this thread on
marc.theaimsgroup.com:
http://marc.theaimsgroup.com/?l=amanda-users&m=108514231301508&w=2
and the thread that ensues
Here's what I get when I look at the appropriate files affecting one of
those backups:
# less runtar.20061107001110.debug
runtar: debug 1 pid 7776 ruid 30 euid 0: start at Tue Nov 7 00:11:10 2006
gtar: version 2.5.0p2
running: /usr/local/bin/gtar: gtar --create --file - --directory
/var/spool/PO/mailbox --one-file-system

--totals --exclude-from
/tmp/amanda/sendbackup._var_spool_PO_mailbox_0-99.20061107001110
.exclude --files-from
/tmp/amanda/sendbackup._var_spool_PO_mailbox_0-99.20061107001110.include
runtar: pid 7776 finish time Tue Nov 7 00:11:11 2006
# less
/tmp/amanda/sendbackup._var_spool_PO_mailbox_0-99.20061107001110.include
./[0-9]/
./[1-9][0-9]/
This begs the question: Can a file as designated by --files-from
contain wildcards? Apparently, they cannot. Apparently GNU Tar is
looking for directories with literal names beginning with ./[0-9]/ and
./[0-9][0-9]/ rather than globbing them to ./0/, ./1/, [...], ./9/,
./10/, ./11/, [...], ./98/, and ./99/
At first glance, GNU tar's documentation appears to say I cannot.
What it all boils down to is this looks less and less like an AMANDA
problem and more and more like a GNU tar problem.
Not having wildcard/globbing like this is not very helpful if I have a
large number of directories here (in this case, 500 of them) and
enumerating them 100 individually at a time is an extreme nuisance. If
anything else, I'd love to know if I'm doing something wrong. Though if
worst comes to worse, I have some ideas based on the distribution copy
of disklist of what I can do in lieu of any wildcards should I be
required to, yet keep my disklist looking reasonably neat and easy to
manage.
Thanks in advance for any tips.
--Ian.
