One problem with this - it will substitute . for _ in all environmental variables.

How about

/^(?i:ORACLE_SID|ORACLE_HST_SID|ORACLE_HOME|SDP_HOME)=/ && s/([^=]+)/(my $lhs=$1) =~ tr:_:.:; $lhs/e for @envArray;

update: better idea by Roy Johnson below. Doh!

However his code doesn't actually work because the brackets are the (?imsx-imsx:pattern) extension. Below is a possible fix:

s/^((?i)ORACLE_SID|ORACLE_HST_SID|ORACLE_HOME|SDP_HOME)(?==)/(my $lhs=$1) =~ tr:_:.:; $lhs/e for @envArray;
