hi, can you please tell me how i can download wget from the linux command line?

i want to download a script into my dedicated server i am leasing from www.webune.com and i need to install a script that i need for my site, but i can't seem to find out how i can install wget on this server. everything works perfect, i just need to know what command i need to install wget in linux though the shell command line.

thank you for your support.
