Check file for string existence before appending it with string
I want to append file with a string but before doing that i want to check if this string already exist in that file.I tried with grep on Solaris 10 but unsuccessful.Man pages from grep seems to suggest if the string is found command status will be 0 and if not 1.But i am not finding it.May be i am doing something wrong here?
I am looking for exist status 1 so that i can use it in if condition

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
