I have a file with a list of packages.
I need to download a ton of packages.
apt-get -d | cat packages.txt
but it just echoes the contents of packages.list.

Working through your command line:
This does not appear to be a valid usage of the command. apt-get requires an 'operation', such as install, update, upgrade. From reading your post, I'm guessing that 'apt-get -d install' is the command you want. This will download, but not install, a dist package.
| cat packages.txt
The '|' is called a pipe, and it simply passes output of the first command as input to the second command. In this case, you are passing the output of 'apt-get -d' to the 'cat' command. This is why you see the contents of packages.list.
Consider trying: cat packages.txt | apt-get -d install
also, you can accomplish the same result with an explicit input redirection operator:
apt-get -d install < packages.txt
NOTE: While testing these commands, consider using the '--dry-run' flag with apt-get. This will prevent apt-get from downloading, but still run through the command output. A very useful debugging technique.
apt-get --dry-run -d install < packages.txt
Does this help?
