Q. I’ve couple of large tarballs such as www.tar and images.tar. Is it possible to extract a single file or a list of files from a large tarball such as images.tar instead of extracting the entire tarball? How do I extract specific files under Linux / UNIX operating systems?
Q. When I run tar command it fails with an error that read as follows:

I’ve downloaded a file from internet in .tgz format. How do I decompress .tgz file under UNIX or Linux operating system using a shell prompt?
Q. I have download files from the Internet. Each file has .gz extension. How do I open .gz files under Linux?
A. You need to use gzip / gunzip program. It is a software application used for file compression. It is based on the DEFLATE algorithm, which is a combination of LZ77 and Huffman coding. DEFLATE was intended as a replacement for LZW and other patent-encumbered data compression algorithms
Use guzip command as follows:
$ gunzip file.gz
OR
$ gzip -d file.gz
To see new file, enter:
$ ls -l
Files with extension tar.gz or .tgz are tar files compressed with gzip. On Unix system extract them with following command:
$ gunzip < file.tar.gz | tar xvf -
$ gunzip < file.tgz | tar xvf -
If you have GNU tar (Linux system) you can use the z option directly:
$ tar xvzf file.tar.gz
$ tar xvzf file.tgz
