aria2c:tldr:d0488

The given command is related to the aria2c tool, which is a lightweight command-line download manager. This command is used to initiate a download with aria2c and has the following components:

• aria2c: This is the command used to invoke aria2c, indicating that we want to use it to download files.
• --split=${number_of_connections}: This flag instructs aria2c to split the file into multiple parts and download them simultaneously using a specified number of connections. The number_of_connections should be replaced with the desired value, indicating the number of connections or threads you want to use for downloading. Increasing the number of connections can potentially speed up the download, but it depends on the bandwidth and settings of the server you are downloading from.
• "${url}": This is the URL or download link of the file you want to download. It should be replaced with the actual URL you want to download from, enclosed in double-quotes.

In summary, the command aria2c --split=${number_of_connections} "${url}" runs the aria2c download manager with the specified settings to download a file from the provided URL.
