Putting Lines to Together.

[bigb89]

Hi Guys,

Sorry if this may seem like a stupid question. I can probably find my answer on google, but I don't know exactly what I should search for. So here's what I would like to do:

Let's say I have a text file containing the following:

Hi,
my
name
is
bigb89.

What could I do to make that same file like this?:

Hi, my name is bigb89.

It doesn't matter the language I use (shell, perl, awk, sed, etc). I just would like know of a way that I can achieve that.

Regards.
