using perl to search and replace

Hope this helps, I created a file prodtest for example

Code:
$ perl -pe 'if ( $_ =~ /hostname/ ) { s/test/prod/ }' prodtest

st oa_var="s_hostname">prod</host>
<host oa_var="s_name">test</host>
<host oa_var="s_hostname">qa</host>
<host oa_var="s_hostname">prod</host>
<host oa_var="s_host">test</host>


$ cat prodtest

st oa_var="s_hostname">test</host>
<host oa_var="s_name">test</host>
<host oa_var="s_hostname">qa</host>
<host oa_var="s_hostname">test</host>
<host oa_var="s_host">test</host>


$ perl -i -pe 'if ( $_ =~ /hostname/ ) { s/test/prod/ }' prodtest


$ cat prodtest

st oa_var="s_hostname">prod</host>
<host oa_var="s_name">test</host>
<host oa_var="s_hostname">qa</host>
<host oa_var="s_hostname">prod</host>
<host oa_var="s_host">test</host>

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 AUTHOR
