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.

dist::zilla::app::command::test

Dist::Zilla::App::Command::test(3pm)			User Contributed Perl Documentation		      Dist::Zilla::App::Command::test(3pm)

NAME

       Dist::Zilla::App::Command::test - test your dist

VERSION

       version 4.300020

SYNOPSIS

	 dzil test [ --release ] [ --no-author ] [ --automated ] [ --all ]

DESCRIPTION

       This command is a thin wrapper around the test method in Dist::Zilla.  It builds your dist and runs the tests with the AUTHOR_TESTING
       environment variable turned on, so it's like doing this:

	 export AUTHOR_TESTING=1
	 dzil build --no-tgz
	 cd $BUILD_DIRECTORY
	 perl Makefile.PL
	 make
	 make test

       A build that fails tests will be left behind for analysis, and dzil will exit a non-zero value.	If the tests are successful, the build
       directory will be removed and dzil will exit with status 0.

OPTIONS

   --release
       This will run the test suite with RELEASE_TESTING=1

   --automated
       This will run the test suite with AUTOMATED_TESTING=1

   --no-author
       This will run the test suite without setting AUTHOR_TESTING

   --all
       Equivalent to --release --automated --author
