What's a script?

[Mark C. Miller]

I'm a newbie and know nothing about programming.  Here's a line I grabbed 
from another thread

quote

Basically, stick your ssh commands in a script. Stick the script in the
appropriate start up file.

What does the author mean by a "script"?  Is this a particular 
programming language?  Once you get it written, whatever you write it in, 
what would be the command to execute it, once I figured out what the 
"appropriate start up file" is?

Sorry to be so basic, but right now if it doesn't have an interface, I 
know little about it.  I'd like to change that.

tnx
