ArchLinux - yaourt: save updatelog?

Question

When I do yaourt -Syu sometimes there is such a long log in the console so that the buffer gets full and some information is lost. As the information is important sometimes I´d like to save everything that´s logged by yaourt/pacman in a file.

Doing yaourt -Syu > file does save things to file, but then you cannot see what´s going on in the console. Is it possible to have both?

Answer 1

Yes, pipe it to tee

From the tee man page:

NAME
   tee - read from standard input and write to standard output and files

SYNOPSIS
   tee [OPTION]... [FILE]...

DESCRIPTION
   Copy standard input to each FILE, and also to standard output.

So your command should be yaourt -Syu | tee yaourt.log

Answer 2

I am normally most interested about what ultimately is installed so I just look at the pacman log located at /var/log/pacman.log. All pacman output is there so you can see if there were any errors or important warnings.
