Tar help with permissions

[santrix]

Believe me, I've looked, but I can't find an answer to this anywhere quickly...

I have tarballs which have the wrong permissions and owners/groups embedded.

When I extract the files, I want to blanket apply a particular user, group, and permissions to files and directories.

Is there a way to do this?

I have tried

tar --owner=newowner --group=newgroup --mode=ugo=rwX -xf archive.tar

but it just extracts the files ignoring any changes to permissions.

Does the user running the tar command have write access to the files?

[santrix]

Yes, it's me

I'm taring up a pile of files off my mac, which obviously has nothing in common in terms of users/groups with my linux web server.

Obviously the ID's associated with my mac account user/group are nonsense once the file is unpacked on the linux box.

Does that make sense?

tar --owner=newowner --group=newgroup --mode=ugo=rwX -xf archive.tar

I'm not sure if this is causing the error must normally Linux commands have a space after a flag rather than an = sign (not always, for example dd doesn't)

You could try:

tar --owner newowner --group newgroup --mode 744 -xf archive.tar

Your mode may be okay but I have never used that method before. I assume you replace newowner and newgroup with ones that exist on your system too?
