if that was the case wouldn't each (this is where the fog lifted) "segment" be replaced by Address_V2?


fulley expanded would be 

s/Address_V1||FromAddr||||315 Benjamin Lane||||Boise||ID||USA||83704/Address_V2/

if I put in single quotes around $_ I get Address_V2 appended to the beginning of $_.

ok nevermind iv apperently been spending to much time at play boy and not thinking.

since I don't have a modifer at the end of the expression it only matches the 1st entry in the expression. with that now clear you are most certenly correct. I should deffinetly be much more explicit w/ the pattern so it is less ?obtuse?

Let's see if I can debug on the fly w/out testing

If that's your input line, then note that it has regex
special characters in it, and they're being treated as
So it's matching "Address_V1" OR an emptry string OR
"FromAddr" OR an empty string OR "315 Benjamin Lane"
OR ....

The first thing it happens to hit is "Address_V1", so
it successfully changes that to Address_V2.

Changing your delimiters away from pipes would yield
more expected results. Alternatively, it'd probably be
good to quote the string first.


To keep those metacharacters from having special
