rar:tldr:72a70
The given command is used to create a RAR archive file with a specific size limit and can include both files and directories.
Let's break down the different components of the command:
rar
: This is the command used to interact with the RAR compression utility.
a
: This argument specifies that we want to create a new archive.
-v${50M}
: This argument sets the maximum size of each volume in the archive. The ${50M}
part means that the size is 50 megabytes (M). This option is used to split the archive into multiple smaller parts, which can be helpful when dealing with large files.
-R
: This argument tells RAR to include the contents of subdirectories recursively. It means that if the filename_or_directory
provided is a directory, it will add all files and subdirectories within it.
${path-to-archive_name-rar}
: This is the path and name of the archive file you want to create, followed by the .rar
extension.
${filename_or_directory}
: This represents the file or directory you want to include in the archive. It can be a single file or a directory with multiple files and subdirectories.
To summarize, the command creates a RAR archive file with a specific volume size limit (-v${50M}
) and includes all the files and directories (${filename_or_directory}
) inside the archive.
