rsync -lptgoDu --delete --files-from=distlist distserver::8.0/i386 /root2
where distlist is
etc/init.d/rsyncd
etc/rsyncd.conf
usr/bin/rsync
usr/bin/rsyncstats
usr/sbin/rcrsyncd
usr/sbin/rsyncd
usr/share/doc/packages/rsync
usr/share/doc/packages/rsync/COPYING
usr/share/doc/packages/rsync/README
usr/share/doc/packages/rsync/tech_report.ps
usr/share/doc/packages/rsync/tech_report.tex
usr/share/man/man1/rsync.1.gz
usr/share/man/man5/rsyncd.conf.5.gz
It should not do /root2/i386/etc/init.d/rsyncd and so on as
-R would have it.
It should not create (flattened)
/root2/rsyncd # from /etc/init.d
/root2/rsyncd.conf
/root2/rsync
/root2/rsyncstats
/root2/rcrsyncd
/root2/rsyncd # from usr/sbin?
/root2/COPYING
/root2/README
/root2/tech_report.ps
/root2/tech_report.tex
/root2/rsync.1.gz
/root2/rsyncd.conf.5.gz
What it should create or update is /root2/etc/init.d/rsyncd and so on.
and it should be equivalent to
rsync -lptgoDu --delete --files-from=distlist \
distserver:/data/distribution/8.0/i386 /root2
or
rsync -lptgoDu --delete --files-from=distlist \
/data/distribution/8.0/i386 client:/root2
If /root2/usr/share/doc/packages doesn't exist it should be
created with perms from source but it should not be recoursed.
This example is drawn from one of the most recent emails
requesting this feature.
I want to thank Wayne for his work on this and his patience
with me. I seem to be butting heads with him while he has
been good enough to actually write code. I hope this points
out clearly the difference in our perspectives on this. I
am not talking about a way to extend the command line. I am
talking about an explicit list that eliminates the tree walk
and awkwardness of artificial include/exclude lists and has
a similar effect to
while read subpath
do
rsync -lptgoD distserver::8.0/i386/$subpath /root2/$subpath
done <distlist
which is what people are actually doing now.
There is i'm sure value in being able to pass a list that
simply won't fit on the command line.
There is however immediate value in being able to request
a sparse list of paths to be synced from one tree to another
without looping or changing CWD (especially on the remote
end).
