add new lines of text before and after each input line
I have a file that contains hundreds of lines such as:

this_is_macro,000001
this_is_macro,000002
this_is_macro,000003

I would like to add the variable words

MACROBEGIN MACRO_000001
MACROBEGIN MACRO_000002
MACROBEGIN MACRO_000003

above each line

and add the word

MACROEND

below each line

to produce

MACROBEGIN MACRO_000001
this_is_macro,000001
MACROEND
MACROBEGIN MACRO_000002
this_is_macro,000002
MACROEND
MACROBEGIN MACRO_000003
this_is_macro,000003
MACROEND

Thanks,
Kenny.

Code:
awk -F, '{ print "MACROBEGIN MACRO_" $2 RS $0 RS "MACROEND" }' file


If you need the pattern, only related to the "macro" records use:

Code:
awk -F, '/this_is_macro/{ print "MACROBEGIN MACRO_" $2 RS $0 RS "MACROEND" ;next}1' file

this will also do
Code:
awk -F, '{print "MACROBEGIN MACRO_"$2"\n"$0"MACROEND\n"}' filename
