Shell I use: /bin/sh
To reproduce try next:
NOTICE i have more than two (as in your example) directories to tar
I have two of them with same begin path: usr/local
usr/local/etc usr/local/virtwww

Здравствуйте, Freebsd-questions.
when
tar -cf file.tar /home/*
It always says:
tar: Removing leading '/' from member names
man tar
-P Preserve pathnames...
But I do not need to preserve. I want to tar without that warning.
How to force tar to be quiet?
MS Don't give the leading '/' in path names. Like so:
MStar -cf file.tar -C / home
MS Cheers,
MS Matthew
# tar -cf /home/kes/backup/conf/aaa_etc.tar -C / boot/loader.conf etc/*
usr/local/etc/* usr/local/virtwww/*
tar: No match.
MS Yep. As shown, you don't need '*' here. tar(1) is perfectly capable of
recursing
MS through a directory hierarchy given only the name of the top level
directory.
MS [ * is actually expanded by your shell, rather than tar, so it's trying to
match
MS filenames against your current working directory, and not against the
directory
MS the '-C' switches tar to.]
And next does not work as expected:
# tar -cf /home/kes/backup/conf/aaa_etc.tar -C / boot/loader.conf etc
usr/local/etc usr/local/virtwww
I get:
boot
etc
mysite
local
sub
usr
virtwww
MS Hmmm... I can't reproduce this locally. If I run:
MSsudo tar -cf foo.tar -C / etc boot
MS then I get (as expected) a tarball with the contents of /etc and /boot --
not
MS only that, but there's nothing printed to stdout/stderr while the command
runs.
MS Are any of the directories concerned symbolic links on your system? tar(1)
MS handles sym-links quite carefully given that it's possible to use them to
MS generate specially crafted tar archives that you can use to trick an unwary
MS admin into overwriting security sensitive files. As a rule of thumb, when
MS specifying directory trees to back-up, try and avoid having any path
components
MS being symbolic links.
Why local, sub, mysite, virtwww are in ROOT or tar???
'local' must be under 'usr'
'virtwww' must be under 'local'
