Hi.

I have a list of IP addresses (one per line) in a text file. I need
to surround them with pipe symbols and include a single space in
between the first and last number.

For example:

[before]
192.168.1.1
<space>
192.168.1.2
192.168.1.3
<space>
192.168.1.4
192.168.1.5

[after]
| 192.168.1.1 |
| 192.168.1.2 |
| 192.168.1.3 |
| 192.168.1.4 |
| 192.168.1.5 |

I tried a few different sed line that didn't work out so well

Thanks in advance....
