This will work for a line, maybe more details will help me...

replace.sh:
Code:
#!/usr/bin/awk -f
FNR==1 { fnum++ }
/^HEADER$/ {h=1;l=0}
h {l++}
l==3 && fnum==1 { p1=$0; next }
l==3 && fnum==2 { print p1; next }
fnum==2 { print $0 }

Code:
[mute@geek ~/test]$ cat fileA
HEADER
some kinda of data aAAaaa
this is the new data aaAAAA
more data etc aaaa

[mute@geek ~/test]$ cat fileB
HEADER
some kinda of data in BBBB
this is the old data bbBBBb
more data etc bBBbBB

[mute@geek ~/test]$ ./replace.sh fileA fileB
HEADER
some kinda of data in BBBB

CXXTESTGEN(1)							    User Manual 						     CXXTESTGEN(1)

NAME
cxxtestgen - Generates test source files for CxxTest SYNOPSIS
cxxtestgen [options] [-o output] <file> ... DESCRIPTION
This script parses the files provided and generates an output source file that can be build with traditional compiler to produce the test- runner executable. OPTIONS
-h --help Show help message and exit. --version Write the CxxTest version. -o NAME --output=NAME Write output to file NAME. -w WORLD --world=WORLD The label of the tests, used to name the XML results. --include=HEADER Include file HEADER in the test runner before other headers. --abort-on-fail Abort tests on failed asserts (like xUnit). --main=MAIN Specify an alternative name for the main() function. --headers=FILENAME Specify a filename that contains a list of header files that are processed to generate a test runner. --runner=CLASS Create a test runner that processes test events using the class CxxTest::CLASS. The currently available runners are: - ErrorPrinter This is the standard error printer, which formats its output to the standard output stream (std::cout). Same as --error-printer. - ParenPrinter Identical to ErrorPrinter except that it prints line numbers in parantheses. This is the way Visual Studio expects it. - StdioPrinter The same as ErrorPrinter except that it uses printf instead of std::cout. - XmlPrinter Print test results to an XML file. - XUnitPrinter This test listener generates output using both ErrorPrinter and XmlPrinter. Same as --xunit-printer. --gui=CLASS Create a GUI test runner that processes test events using the class CxxTest::CLASS. (deprecated) --error-printer Create a test runner using the ErrorPrinter class, and allow the use of the standard library. --xunit-printer Create a test runner using the XUnitPrinter class. --xunit-file=XUNIT-FILE The file to which the XML summary is written for test runners using the XUnitPrinter class. The default XML filename is TEST-<WORLD>.xml, where <WORLD> is the value of the --world option. (default: cxxtest) --have-std Use the standard library (even if not found in tests). --no-std Do not use standard library (even if found in tests). --have-eh Use exception handling (even if not found in tests). --no-eh Do not use exception handling (even if found in tests). --longlong=TYPE Use TYPE as for long long integers. The default is for 'no' long long integer type to be specified, which is consistent with the current C++ standard. --no-static-init Do not rely on static initialization in the test runner. --template=TEMPLATE Generate the test runner using file TEMPLATE to define a template. --root Write the main() function and global data for a test runner. --part Write the tester classes for a test runner. -f --fog-parser Use new FOG C++ parser (Python 2.7 is required).
