How to compress the whole directory using xz and tar

To compress a directory using xz and tar, you can use the following steps:

1. Navigate to the directory that you want to compress.

cd /path/to/directory

2. Create a tar archive of the directory.

tar cf directory.tar *

This will create a tar archive named directory.tar that contains all the files and subdirectories in the current directory.

3. Compress the tar archive using xz.

xz directory.tar

This will create a compressed file named directory.tar.xz that contains the tar archive.

4. Optional: delete the original tar archive.

rm directory.tar

This will remove the original tar archive, leaving only the compressed file.

Note that these steps will create a compressed file that contains a single tar archive. If you want to compress multiple directories or files into a single compressed file, you can specify multiple arguments to the tar command, or you can use the -C option to change to a different directory before creating the tar archive.

For example, to compress multiple directories into a single compressed file, you can use the following command:

tar cf - directory1 directory2 | xz > directories.tar.xz

This will create a compressed file named directories.tar.xz that contains a tar archive of both directory1 and directory2.

You can also use the -C option to specify a different directory for each file or directory that you want to include in the tar archive. For example:

tar cf - -C /path/to/directory1 . -C /path/to/directory2 . | xz > directories.tar.xz

This will create a tar archive that contains the contents of directory1 and directory2
