Replace string and delete extra characters
Hopefully someone can help out here. This is probably fairly basic, but I've searched and tried several variations of the solutions presented in these forums, so I'll go ahead and ask.
How can I locate a string in a file, delete the characters after the string and then replace the string with a new string?
Currently I have this, which is getting me close to a solution, but I can't get the extra characters removed:
for file in test_program; do
sed 's/OUTPUT='/'OUTPUT='$file/g $file > new_$file
done
Here is the test_program file that I am testing with:
This is a test
This is a test
/OUTPUT=("This is a test")
This is a test
Here are the results after running my script:
This is a test
This is a test
/OUTPUT=test_program("This is a test")
This is a test
I just need to have the script get rid of ("This is a test") and it will work fine for what I am trying to do, which is make this change to several thousand files at one time. Any assistance would be appreciated. I've got other ways to do this, but now that I've embarked down the Unix path, I want to see how this is done.

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.
