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

set_color(1) fish set_color(1) NAME
set_color - set_color - set the terminal color set_color - set the terminal color Synopsis set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR] Description Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple, cyan, white and normal. o -b, --background Set the background color o -c, --print-colors Prints a list of all valid color names o -h, --help Display help message and exit o -o, --bold Set bold or extra bright mode o -u, --underline Set underlined mode o -v, --version Display version and exit Calling set_color normal will set the terminal color to whatever is the default color of the terminal. Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey font color, while set_color --bold white will result in a white font color. Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator. set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of ncurses and recompile fish against it in order to fix this issue. Version 1.23.1 Sun Jan 8 2012 set_color(1)
