lbzip2 uncompress tar file-CodePudding

I compressed a folder with many subfolders ( about 50GB)

Compression:

tar -cjf test.tar.bz2 test

unzip:

lbzip2 -k -d -n 5 test.tar.bz2 ~/temp/

Why the output is a .tar file ? I'm searching on google but I'm confused I expect a uncompressed folder

Thank you

These might help:

# Compress a folder with many subfolders and files.
function compress() {
    # Get the name of the folder to compress.
    echo "Enter the name of the folder to compress:"
    read folder
    # Get the name of the compressed file.
    echo "Enter the name of the compressed file:"
    read file
    # Compress the folder.
    tar -czf $file $folder
}

# Decompress a tar file into a folder using lbzip2.
function decompress() {
    # Get the name of the file to decompress.
    echo "Enter the name of the file to decompress:"
    read file
    # Get the name of the folder to decompress into.
    echo "Enter the name of the folder to decompress into:"
    read folder
    # Decompress the file.
    lbzip2 -d $file
    # Extract the file.
    tar -xzf $file -C $folder
}

tar -xjf test.tar.bz2

That will run bunzip2 to decompress and it will extract the contents of the tar file.

If you feel the need to specifically use lbzip2 for decompression, then:

lbzip2 -dc < test.tar.bz2 | tar xf -
