current date

The following command will create a compressed tar archive for each folder found in the current directory.
It will use the LZMA/LZMA2 compression algorithms and it supports Unix-like file system metadata as well.
It will reuse the name of the folder for the archive as well and it will append the current date to the name.

find . -maxdepth 1 -mindepth 1 -type d -exec tar cJf "{}.`date +%F`.tar.xz" '{}' \;

The parameters we used for the find command are the following:

• -maxdepth levels Descend at most levels (a non-negative integer) levels of directories below the command line arguments. -maxdepth 0 means only apply the tests and actions to the command line arguments.
• -mindepth levelsDo not apply any tests or actions at levels less than levels (a non-negative integer). -mindepth 1 means process all files except the command line arguments.
• -type d Match directories (folders) only

The parameters we used for the tar command are the following:

• -c create a new archive
• -J filter the archive through xz (compress the archive using the xz lossless compression program)
• -f file use archive named file
