That's a terrible node title. Help will come when it does, and "Help?" says nothing about what you're asking. 

my $filename = "/wek/hep/bin/defaults.import";
$filename =~ s/(defaults)(\.import)/$1$ENV{APPL_ENV}$2/;

Note, environment variables are considered tainted data by taint mode, and using raw, unchecked ENV data in a filename can be risky.
