Sometime, some sysadmins forget one little detail about UNIX tar and make archives with leading slash. This can be helpful when you try to restore fast some files or directories, but in most of the cases is very bad habit. In many cases it's just need to extract somewhere (but not on the original place) file and compare it with the current file. So you have archive with leading slash and want to extract something. Let do it on a little complicated, but safe way:
mkdir -p /tmp/lib
for i in `ldd /usr/bin/tar|awk '{print $3}'`;
do
cp $i /tmp/lib
done
cp /usr/bin/tar /tmp
mkdir -p /tmp/usr/lib
cp /usr/lib/ld.so.1 /tmp/usr/lib
chroot /tmp ./tar xvf archive.tar
In the man page, I get the idea, (SUN Solaris chroot) was mentioned full list of so libraries, but I am lazy and hate to write. And want to avoid mistakes. BTW in the documentation is not mentioned ld.so library and without this library tar do not want to run :-)
P.S. The script was tested only on Solaris 10, but (depend of format of ldd) will work on other UNIXes and Linux
P.P.S. You can use pax or GNU tar but as they are not a standard in UNIX world I try to make my solution universal
