You could redirect the output to a Output_file as follows then.
Code:
awk 'FNR==NR{A[$1]=$1;next} ($1 in A){print}' pattern_file FS=";" main_file > Output_file
Thanks,

I know i can redirect the output but it still did not remove the lines from the main file. Sorry if that was unclear before.
Omg you are fast with editing . I tested the revised code and it seems to work fine. I now have 2 files with different output in each. I will test it some more with other files to be sure but it seems to work. Thank you again for the extremly fast helping.
I want to search a file for a string and then if the string is found I need the line that the string is on - but also the previous two lines from the file (that the pattern will not be found in)

wibble-test-genrunner
wibble-test-genrunner(1) General Commands Manual wibble-test-genrunner(1)NAME
wibble-test-genrunner - Code generator for wibble testsuites.
SYNOPSIS
wibble-test-genrunner header <file>
wibble-test-genrunner main <files>
DESCRIPTION
The program generates .cpp files that are then compiled and linked into a test program for running tests from .test.h files. Examples of
such .test.h files may be found among wibble headers, eg. /usr/include/wibble/regexp.test.h.
In the first form, the program processes a single header file (usually of the form foo.test.h) and produces a corresponding .cpp file to be
compiled. In the second form, it takes as <files> all the .test.h headers and produces a single main.cpp which contains the main() function
of the test program, which then runs all the tests in all the .test.h files. The generated source code is always written to standard output
and it is left up to the user to redirect it to a meaningful location.
The program currently has no options other than the two forms above. The program is intended to be run as part of build process of programs
or libraries using the wibble testing framework. For convenient use from CMake, there is a test.cmake script under /usr/share/wibble, that
takes care of producing all the .cpp files (both per-header and the main one), compiling them and linking them into a single binary which
executes the testsuite.
