How can I add borders

Question

Given this, how can I add a border around?

\begin{ttfamily}
\begin{lstlisting}
g@g0001:~$ cd Desktop
g@g0001:~/Desktop$ cat script.sh

#!/bin/bash
echo $1 `date`

g@g0001:~/Desktop$ ./script.sh "hello"
hello Wed Dec 19 06:30:49 CET 2012

g@g0001:~/Desktop$ ./script.sh "`ls -la`"

\end{ttfamily}

I tried \fbox but I get an error.

Are you trying to achieve something like this?

Here, the frame was achieved with the frame option with value single. The default value is none. You can choose from other values: leftline, topline, bottomline, lines, or shadowbox. Also, you don't need to put your listings inside \begin{ttfamily}...\end{ttfamily} as this can be set by the option basicstyle. The font styles can be achieved through options among others basicstyle, keywordstyle, numberstyle, identifierstyle, commentstyle, etc. You can set these and more.

Consult the listings manual (specifically Section 4.6 and 4.11) by clicking on this link or by entering texdoc listings in your terminal. For a full set of frame options, see Section 4.11.
