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>

NAME
App::Prove::State::Result::Test - Individual test results. VERSION
Version 3.28 DESCRIPTION
The "prove" command supports a "--state" option that instructs it to store persistent state across runs. This module encapsulates the results for a single test. SYNOPSIS
# Re-run failed tests $ prove --state=failed,save -rbv METHODS
Class Methods "new" Instance Methods "name" The name of the test. Usually a filename. "elapsed" The total elapsed times the test took to run, in seconds from the epoch.. "generation" The number for the "generation" of the test run. The first generation is 1 (one) and subsequent generations are 2, 3, etc. "last_pass_time" The last time the test program passed, in seconds from the epoch. Returns "undef" if the program has never passed. "last_fail_time" The last time the test suite failed, in seconds from the epoch. Returns "undef" if the program has never failed. "mtime" Returns the mtime of the test, in seconds from the epoch. "raw" Returns a hashref of raw test data, suitable for serialization by YAML. "result" Currently, whether or not the test suite passed with no 'problems' (such as TODO passed). "run_time" The total time it took for the test to run, in seconds. If "Time::HiRes" is available, it will have finer granularity. "num_todo" The number of tests with TODO directives. "sequence" The order in which this test was run for the given test suite result. "total_passes" The number of times the test has passed. "total_failures" The number of times the test has failed. "parser" The underlying parser object.
