UNIX for Dummies Questions & Answers

I have a tar file that I need to extract a single file to the current directory. The file I want to extract is located in the tar at the following path inside the tar file: repository/parts/SDCG.tgz

I use the following command to extract the file:
tar xf delivery.tar repository/parts/SDCG.tgz

It successfully extracts the file, but it puts in the current directory as repository/parts/SDCG.tgz. But what I want is just SDCG.tgz.

Is there a way for me to extract that single file to my current directory?

Thanks,
Robert

You havent been searching the forum very much have you?

There are many threads e.g.

Ok, I looked a the post you pointed me to and I was able to get pax to work, but I didn't realize that pax works with .tar files but not .tgz files. When I first tried it on my .tgz file it gave all kinds of errors so I initially didn't think pax would be able to help me.

So I had to do a gunzip of my .tgz file.

I did the command: gunzip x.tgz
which replaced the file x.tgz with x.tar

The file I wanted to extract from the tar file was in path repository/parts/RDAP.tgz.

I did the following command:

Code:

pax -r -d repository/parts/RDAP.tgz -s'/repository\/parts\/RDAP.tgz//p' -f x.tar

this -s option allowed me to subtitute the path repository/parts/ with nothing. The file extracted to my current directory which is exactly what I wanted. Note that \/ is an escape sequence or /.

I am posting this in case someone else is looking to do the same thing.
