linux tar
I have a huge tar 'tgz' file -- it is compressed using gzip tar option. I want to delete a few files like a/b/c/d* from it.
As I try do delete
tar -f mytar.tgz --delete 'a/b/c/d*'
It gives the following error message.
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Archive contains obsolescent base-64 headers
tar: Archive contains `\033L\254\343\360\303\302
tar: Skipping to next header
tar: a/b/c/d*: Not found in archive
tar: Error exit delayed from previous errors
I tried z option also but to no avail. I certainly don't want to extract the whole tar to remove those files.

This is not a straight tar archive, it´s a '.tar.gz' as its name and error message shows. You´ll need to give it a decompress option. I am not sure whether deletion works on compressed archives. Never tried it.

Well append and delete works on tar and are very vital operations if you are dealing with huge tars.
Delete worked for me after I did gunzip on my tar. But since it was huge, it took extra time doing and the recompressing it. I simply wonder if there is a way to eliminate that extra drill

you could try specify:
tar -zf
this tells tar that the archive is compressed.

Well, i tried it and it gave me:
tar: Cannot update compressed archives
Try `tar --help' or `tar --usage' for more information.
so, I guess no luck, seems as you have to unzip it before update/delete operations can be done.

Here is an example of creating an archive and extracting a single file from it.
If you use tar -xvf path
that will extract your file
If you use tar -xvf path
that will extract your file
[jhelfman@eggman ~]$ tar -cvf test.tgz tmp/
a tmp
a tmp/expert.html
a tmp/error
[jhelfman@eggman ~]$ cd ugh/
[jhelfman@eggman ~/ugh]$ ls

Ok. Thanks all.

The only question now is about Arnold's fancy redirection. Is it going to take drive space equal to = tar + tar.gz?
It usually runs in RAM until it needs to swap :)
Ah, sorry, misunderstood your question!
Yes, you will need space for the old file as well as the new one you have created without needed files.
