xz:tldr:408b9
This command is using the xz utility to decompress a file that is in the LZMA format.
Here's a breakdown of the command:
xz: This is the command itself, which is used for compression and decompression using the LZMA and XZ formats.
-d: This is an option for the xz command, specifying that we want to decompress the file.
--format=${lzma}: This option specifies the format of the input file. ${lzma} is likely a variable representing the LZMA format. This option tells xz to expect a file in the LZMA format.
${file-lzma}: This is a variable that represents the path or name of the input file in the LZMA format. It is passed to the xz command to indicate the file to be decompressed.
In summary, the command xz -d --format=${lzma} ${file-lzma} is used to decompress a file in the LZMA format using the xz utility. The specific LZMA file to be decompressed is provided through the ${file-lzma} variable.
