However, if you are a Window's user, you will need additional software to extract a TAR.GZ file. How to Compress Files in the ACC.
If you want to gzip a file or a directory, you can do it by running a simple command using Terminal.

You can create a single archived compressed file using one command to get .tar.gz file or .tar.bz2 files. Tar command can be also used to extract archived files.
Let's see tar command in action through some practical examples.
1) Create .tar archive file
To create an uncompressed tar (.tar) , use -c option with tar command as following:
Where '/path/to/foo.tar' is the location of resulting tar file, and '/path/to/foo' is the location of the file or directory to use as input.
Example
You can use an absolute path instead of relative as shown in the example.
2) Create a .gz archive with tar
The command syntax to create a .gz archive with tar is:
Where '/path/to/foo.tgz' is the destination compressed file, and '/path/to/foo/' is source directory or file to be compressed.
3) Create a .bz2 archive
The option -j is used to work with .bz2 archives.
4) Create a .gz archive and exclude
We use --exclude tar option to exclude a specific extension or list of file extensions. The syntax is similar to below:
5) Use tar with no absolute path on compress
When using tar to compress files and you provide an absolute path, a compressed file will have a full path in its metadata, So when you extract the content, it will be in directories similar to the absolute path that was passed. To avoid this, add a . at the end of the command.
6) Tar all files starting specific letter
Create a tar archive of everything in the current directory starting with an 'i'.
7) Append new file to existing tar archive
Append a file or add a new file to existing tar archive.
The above command will append an anaconda-ks.cfg file in the backup.tar archive
8) Adding two archive files with concatenate option
The above command adds the content of the fullbackup.tar to backup.tar archive.
9) Extract .tar archive file
To extract an uncompressed archive which often has an extension .tar, the command syntax is:
Where /path/to/foo.tar is the absolute/relative path to the location of a tar file. E.g
10) Extract a .gz archive
To extract a .gz archive, we use the command syntax:
Where '/path/to/foo.tgz' is the absolute or relative path to the compressed file.
11) Extract a .bz2 archive

Note that you can pass a .tgz file as long as it was compressed with a -j option. Tar will auto-detect the format and uncompress it.
12) Extract a .tar in specified Directory
To extract a tar archive to a specific directory, use -C option to provide destination directory.
13) Extract file from tar archive
Mac os high sierra cannot be installed on macintosh hd. The following command extracts the 'anaconda-ks.cfg' file in the 'backup.tar' archive.
14) List contents of .gz archive
Suppose you only want to view the contents of a .tgz file without extracting them, you'll use the command syntax:
Just replace '/path/to/foo.tgz' with correct path of your .tgz file
15) List content of .bz2 archive file
If you would like to just view the content of .bz2 archive without extracting, use the command:
16) Preserve symbolic links using tar command
Use tar -cvhf to preserve my symbolic links when generating a tar archive (Use the option 'h' for that).
