The tip of today consists of a command line tool that will help us pre-arrange the download time of a file. That means we delay the download at a specific time in the future. The command is tested under Ubuntu and Debian.
Open the Terminal and run this command to delay the download of a file:
echo 'wget file_link' | at 19:30
Replace "file_link" with the URL of the file you want to download. Also, replace 19:30 with the desired time. The output will be something like this:
~$ echo 'wget http://download.macromedia.com/pub/labs/airlaunchpad/airlaunchpad_p8_3-0-1_081911.air
> ' | at 19:30
warning: commands will be executed using /bin/sh
