Unix Script with line number at beginning of each line.

Could anybody help me.
I need to create a script that reads a text file from STDIN and prints out the file to STDOUT with line numbers at the beginning of each line.

Thanks.

sed '/./=' filename | sed '/./N; s/\n/ /'

# count lines (emulates "wc -l")
sed -n '$='

Question

How do I run this on the Unix Terminal?
# count lines (emulates "wc -l")
sed -n '$='

You can also do :
Code:
cat -n /path/to/file

In The terminal. It shows that I do not have a file or directory with that name.
cat -n /path/to/file

Thanks for any help you could give me.

/path/to/file is an example file name not a real file name

A complete filename (example, not real) is /home/mascorro/text.lis
The path is /home/mascorro
the file is named text.lis

Plus vgersh99 gave you the answer

Code:
nl <filename of your choice goes here>
