Unix (officially trademarked as UNIX, sometimes also written as Unix) is a multitasking, multi-user computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Brian Kernighan, Douglas McIlroy, Michael Lesk and Joe Ossanna.

and add depending on your Ubuntu version either
For Ubuntu 10.04 Lucid:
deb http://nginx.org/packages/ubuntu/ lucid nginx
deb-src http://nginx.org/packages/ubuntu/ lucid nginx
For Ubuntu 12.04 Precise:
deb http://nginx.org/packages/ubuntu/ precise nginx deb-src http://nginx.org/packages/ubuntu/ precise nginx

When using the public nginx repository for Ubuntu, you’ll get this error
W: GPG error: http://nginx.org lucid Release: The following signatures
couldn't be verified because the public key is not available: NO_PUBKEY ABF5BD827BD9BF62
First of all this is only warning and you can ignore it, if you know what are you doing and in case you prefer to add public key, used for signing packages and repository, just run:
gpg -a --export 7BD9BF62 | sudo apt-key add -
wget http://nginx.org/packages/keys/nginx_signing.key cat nginx_signing.key | sudo apt-key add -
apt-get update should now run fine, however after running an
apt-get install nginx
you may still get this kind of error:
dpkg: error processing /var/cache/apt/archives/nginx_1.2.2-1~precise_amd64.deb (--unpack): trying to overwrite '/etc/logrotate.d/nginx', which is also in package nginx-common 1.1.19-1 dpkg-deb: error: subprocess paste was killed by signal (Broken pipe) Errors were encountered while processing: /var/cache/apt/archives/nginx_1.2.2-1~precise_amd64.deb
just remove nginx-common and retry
apt-get remove nginx-common

Some useful Bash Linux alias taken from my user profile. If you have a long command that you type frequently consider putting it in as an alias.
In computing, alias is a command in various command line interpreters (shells) such as Unix shells, 4DOS/4NT and Windows PowerShell, which enables a replacement of a word with another string. It is mainly used for abbreviating a system command, or for adding default arguments to a regularly used command. [WikiPedia]
For day to day hacker, they may be more elegant ways to do it (PERL, AWK), but they have work well for me.
