The command lzop -d ${filename}.lzo is used to decompress a file that has been compressed using the LZO compression algorithm.

Here's a breakdown of the command:

• lzop is the name of the command-line tool used for compressing and decompressing files using the LZO algorithm.
• -d is an option that specifies that the command should perform decompression.
• ${filename} is a placeholder that represents the name of the file you want to decompress. You need to replace it with the actual filename without the extension.
• .lzo is the file extension that indicates the compressed file format. The ${filename}.lzo expression is used to specify the filename with the '.lzo' extension appended to it.

So, when you run the command, it will decompress the file ${filename}.lzo and create the original uncompressed file.
