How to download files and make your computer shutoff...

Open up a cosole... login as root
i.e.
depending on your distro

Then enter your password
now cd to where you want your downloads to be in...

or where ever you want your files

Then get the downloads urls you want and type this is console

Then press enter

And you can leave your computer running knowing that it will turnoff when your done!

--- Make sure you have the wget package installed!

is "poweroff" safe ? I don't know this command. Does poweroff sync the filesystem cache ?
I usually don't use poweroff, I "shutdown -g 0 -h"

No !!!!!
No No No No No....
NOOOOOOOOOOOOOOO.

This is a security problem.

wget does NOT need root privilages to download files to your home directory.
any bugs in wget that allow arbitary code to run would run as root.

as a normal user, the damage an attacker can do is limited.. as root, an attacker could install root kits and other nasties !


The correct thing to do, would be to set SUID on /sbin/shutdown, and as a NORMAL user..



or setup sudo to allow normal users to run shutdown as root and use


ALSO.... use of the '&&' would prevent the machine from shuting down if the download fails (think of the electiricity bill)
use ';' so that the shutdown will run whenever wget exits (even with EXIT_FAILURE)

Also, maybe pipe wget stdout so that you can confirm that the download finished succesfully when you reboot.
