Since I was asked to release it, here it is, my quick and dirty port of
Gnu-tar 1.10. Since it works with my ixemul.library, it fully supports links,
altough the recognition of hard links is currently not working, because of
bugs/limitations in their current implementation in AmigaDOS.
Since it was a quick port, I didn't bother to support compressed tars, this
is something for a later version of the library that supports more process
control stuff than the current one.
I included one Amiga specific option, `-a' or `+amiga-perms', this includes
the full protection long word of every file in the otherwise unused parts
where Unix stores major/minor numbers for devices. Thus if you do
cd DH0:
tar ac .
Then your DH0: partition if stored to `tape:r1000', the default tape device,
that uses Matt's excellent tape-handler (which does a great job on double
buffering tape access). The `a' option guarantees that all information about
your files is stored to tape (file comments are discarded, but who uses them
anyway ;-)). When doing
tar atv
You can see that instead of Unix permissions the Amiga permissions are
displayed.
Restoring is done similarly:
cd DH0:
tar ax
I'm using this tar for own backups, and I don't use any options but the
ones described. I'm pretty sure, there are still tons of bugs in the program,
in options I never even tried, so be careful.
I know particularly, that the program still has problems with device:
notation, and wildcards operating on top of such devices. That's why I'm
using
tar ac .
and not for example
tar ac *
As in the latter case the toplevel files can't magically be accessed.
DON'T FORGET TO INSTALL THE ixemul.library, if you don't already have it
installed from one of my previous distributions.
This program is distributed under the GNU Copyright license, read all of it
in the COPYING file that comes with this archive, read the README file for
the original comments distributed with the Unix archive.
