Tar Directory Structure

16:37:31 <blkperl> hmm so how do you tell tar from 1998 to only tar the directory structure

16:38:29 <haus> port update tar?

16:38:42 <haus> or...yum update tar

16:38:43 <anakha> I don't think that's an option :)

16:41:22 <marut> mkdir tmp && cd tmp && ( cd .. && find . -type d ) | xargs mkdir -p && rmdir tmp && tar -cvf dirstructure.tar .

...rewind...

mkdir tmp && cd tmp && ( cd .. && find . -type d ) | xargs mkdir -p && rmdir tmp && tar -cvf dirstructure.tar .

...oh yeah.

pkginfo y u no read stdin

package_file="$(mkfifo tempfifo && (gunzip -c "packagename.pkg.gz" > tempfifo &) && pkginfo -d tempfifo | awk '/application / {print $2}')"

ZFS chmod -R and what not to do

Suppose you need to recursively apply a ZFS ACE to a directory structure. This is what you should not start by doing:

find . -type d -exec chmod -R A+group:videocat:r-x---a-R-c--s:-d----:allow {} \;

The problem is the -R. Guess what that does. :)

Chant fix!

for each in `find . -type d`; do while ls -dV $each | grep videocat > /dev/null; do chmod A0- $each; done; done;
