aria2c:tldr:e320b

The command you provided is for the aria2c program, which is a lightweight command-line download manager. Here's an explanation of the different parts of the command:

• aria2c: This is the executable command for the aria2c program.
• --force-sequential: This option tells aria2c to download the files sequentially instead of in parallel. By default, aria2c downloads files in parallel to speed up the process, but using this option will ensure that the files are downloaded one after another.
• ${false}: This is a variable placeholder that is commonly used in scripting languages like bash. In this context, ${false} is meant to represent a boolean value of false. By using this placeholder, you can easily change the value from true to false or vice versa.
• url1 url2 ---: These are the URLs of the files you want to download. You can add multiple URLs separated by spaces. The --- at the end is optional and can be used to signify the end of the URLs list.

To use this command, you would replace ${false} with either true or false, depending on whether you want to enable or disable the sequential download. Then you would replace url1, url2, etc. with the actual URLs of the files you want to download.
