# A shell script that builds a 'tartest' directory containing a
# variety of different types of files to see how different tar
# commands handle certain issues.   You'll probably need to edit
# this script to get it to run on your system (in particular, the
# ACL tests below need the name of a valid user and group on your
# system).  Just delete anything that's not valid on your system.
#
# After running this script, create a tar archive with something like:
#
#      tar cf tartest.tar tartest
#      gzip tartest.tar
#
# Please check the documentation for your tar command to see if there
# are options that cause it to archive additional attributes.  For
# example, SunOS8 tar has "extended" mode, star has a number of
# options to enable storage of ACLs, file flags, etc.  Please enable
# any such options that you find.
#
# To double-check, unarchive the result into a separate directory and
# check what file attributes were actually preserved.  You'll probably
# need to include special options to get it to restore
# permissions/owners, etc.  (Many tar commands can't archive links to
# files with long names, for example; only a few can archive ACLs or
# other extended permissions.)
#
# Feel free to edit this file to add additional file types or file
# permissions or to modify the syntax of particular commands to work
# on your particular system.

# P.S. I'm especially interested in any archives that are not correctly
# restored by the following command:  bsdtar xvpf tartest.tar
