I am using:
user@unknown:~$ sudo command -option > log
to save the results of "command" to the file "log", but I'd like to also get the result on the terminal, is this possible?
I am using ubuntu 10.04 lts.

Use tee.
user@unknown:~$ sudo command -option | tee log

Easy to remember if one thinks of the output being split by an upper case "T". E.g. https://en.wikipedia.org/wiki/Tee_(command)#/media/File:Tee.svg

The command you're looking for is 'tee' which makes a data connection similar to a pipe-tee. it sends data two ways. So
sudo command -option | tee log
would tee the command output to both the file 'log' and to stdout, in this case, your terminal.

You can also use script [ http://linux.die.net/man/1/script ] to capture everything that occurs in your terminal session.
Script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive session as proof of an assignment, as the typescript file can be printed out later with lpr(1).

@Excellll Age is irrelevant. I flagged this as the duplicate because I believe that the other has a superior answer.
