In order to extract a specific file from gzip compressed archive tarball you first need to know the full path to this file. Consider a following example.

$ tar tzf to-gzip.tar.gz
to-gzip/
to-gzip/file10.txt
to-gzip/file9.txt
to-gzip/file8.txt
to-gzip/file7.txt
to-gzip/file6.txt
to-gzip/file5.txt
to-gzip/file4.txt
to-gzip/file3.txt

Here is a quick config tip on how to compress and extract files using RAR archive utility. First let’s see how we can compress directory using RAR. In our example we have a directory called my_files containing five files:

$ mkdir my_files
$ touch my_files/file{1..5}
$ ls my_files/
file1  file2  file3  file4  file5

To compress entire directory using RAR archive tool we use rar’s a command. The below command will create a RAR archive called my_files.rar containing all five above files:

$ rar a my_files.rar my_files/

Creating archive my_files.rar

Adding    my_files/file5                                              OK 
Adding    my_files/file4                                              OK 
Adding    my_files/file3                                              OK 
Adding    my_files/file2                                              OK 
Adding    my_files/file1                                              OK
