Extract .tgz files that only contain a pattern
Let's say I've got File.tgz that contains:-

Apple.txt
Banana.txt
Carrot.txt
AppleBanana.txt

Now, I would like to only extract files that contain the patter "Apple".

I've tried this

tar -xvf File.tgz 'tar -tf File.tgz | grep 'Apple''

but it does not work. Please help. Thanks.

Code:
 
gunzip < File.tgz | tar xvf - Apple.txt AppleBanana.txt

Hi Vi-Curious. Your code does work, but not exactly what I was looking for. On most occasions, I don't know the exact filename inside the .tgz file to extract. Hence, the grep.

It's taking me days, and I still have not figured it out. Please help. Thanks.

I don't know how it could be done with a single command. The best I can give you is this:

Code:
 
gunzip < File.tgz | tar tf - | grep Apple > extract
gunzip < File.tgz | tar xvf - -I extract

Thanks Vi-Curious. For now, I think I shall use multiple lines to do what I want. Thanks so much!

I think what you originally had in mind would have been something like this:

Code:
tar -xvf File.tgz `tar -tf File.tgz | grep 'Apple'`

Note those are back (grave) quotes (ASCII 96) not regular quotes.
