The command "gunzip --keep ${archive-tar-gz}" is used to decompress a file or multiple files with the ".tar.gz" extension. Here's the breakdown of the command:
-
"gunzip" is a command-line program that is used for decompressing files. It is often used to extract files from archives compressed with the gzip compression algorithm.
-
"--keep" is an option used with the gunzip command. It tells the command to keep the original compressed file(s) after decompression. By default, gunzip removes the original file after successfully decompressing it.
-
"${archive-tar-gz}" is a placeholder for the name of the file or files you want to decompress. In this case, it is a variable, and its actual value will depend on how it's defined or passed to the command. If you execute this command directly, you need to replace "${archive-tar-gz}" with the actual filename(s) you want to decompress. For example, if you want to decompress a file called "archive.tar.gz", you would replace "${archive-tar-gz}" with "archive.tar.gz".
So, when you execute this command, it will decompress the specified ".tar.gz" file(s) while keeping the original compressed file(s) unchanged.
