Unhappy How to insert some constant text at beginig of each line within a text file.

Dear Folks ,

I am new to UNIX scripting and I do not know how can I insert some text in the first column of a UNIX text file at command promtp.
I can do this in vi editor by using this command :g/^/s//BBB_

e,g I have a file named as Test.dat and it containins below text:

michal
David
Lisa
Antonio

Now I want to insert BBB at the beging of every line and out put should look like belwo:

BBB_michal
BBB_David
BBB_Lisa
BBB_Antonio

Is there are way by using sed, awk or any other command I can get the above out put file. I want to run this command at UNIX command prompt.

Please advice & your feed back is highly appreciated.

Many thanks

Kind Regards

M.Afzal
