Linux command download utility

Linux command download utility:

aria2c -s10 http://example.com/ >/dev/null 2>&1 &

which means

    -s10: using 10 connections
    Redirecting stdout to /dev/null
    Redirecting stderr to wherever stdout is going, which is currently /dev/null because of 1.
    Last &: start a new process in the background

In this case both stdout and stderr will be sent to /dev/null.
Note

aria2c will immediately create a file in the destination with the same size as the file to download. It will fill this file as the download stream comes in. If you abort a download, make sure to also remove the file in the destination.
