try on your machine

This command is used to extract the contents of a compressed tar archive file (.tar.lz4) in a Linux or Unix system.

Here's a breakdown of each part of the command:

lz4: This is the command to decompress a file using the LZ4 compression algorithm.
-dc: These options are used to decompress and output the result to the standard output instead of a file.
${dir-tar-lz4}: This is a placeholder variable that needs to be replaced with the actual path and filename of the compressed tar archive file you want to extract.
|: This symbol is called a pipe. It is used to redirect the output of the previous command (lz4 decompression) to the input of the next command (tar extraction).
tar: This is the command to extract files from a tar archive.
-xv: These options are used to extract the files from the tar archive while displaying a verbose output that shows the names of the files being extracted.

Overall, the command decompresses the specified lz4 compressed tar archive file and then extracts its contents using the tar command.
