The given command:

axel ${url} -o ${filename}

is a command-line instruction that likely involves a tool called "axel" to download a file from the internet.

Here's an explanation of each part:

• axel: This is the name of the tool or command (executable) being used. Axel is a command-line download accelerator that allows multiple connections to a file for speeding up the download process.

• ${url}: This is a placeholder for the URL (Uniform Resource Locator) of the file you want to download. The actual URL should be provided within the command. For example, if you want to download a file from "https://example.com/file.txt", you would replace ${url} with https://example.com/file.txt.

• -o ${filename}: This option specifies the output file name. ${filename} is a placeholder for the desired name of the downloaded file. You should replace ${filename} with the desired file name or path. For example, if you want to name the downloaded file "myfile.txt" and store it in the current directory, you would replace ${filename} with myfile.txt.

Overall, the command is used to download a file from the given URL using the axel tool and save it with the specified file name.
