Hello Wise Monks,
I'm trying to find a more efficient solution, to correct interpolated data coming into my script.
Since I cannot control the data coming in - only how its stored in the database.
I'm storing data into a SQL database that is interpolating domain accounts into whitespace.

Incoming data, 3 types of samples interpolated: 

"AD\thomas"  -> "AD    homas" # tab
"MAIN\nancy" -> "MAIN         
                 ancy"        # newline
"nancy"      -> "nancy"       # no domain, no problem

Here is what I came up with, but its a kludge, and not efficient when working with lots of database inserts. 

$domainID =~ (s/(AD|MAIN)\n/n/);   # should not be
$domainID =~ (s/(AD|MAIN)\r/r/);   # checked 3 times
$domainID =~ (s/(AD|MAIN)\t/t/);   # before exiting

Thanks to everyone's suggestions, I solved this domain interpolation issue: 

our %whitespace = ( "\f" => "f","\n" => "n","\r" => "r","\t" => "t" );

$netid =~ (s/(\s)/$whitespace{$1}/g);
$netid =~ (s/(AD|MAIN)//);

Results:

"AD\thomas"  -> "thomas"
"MAIN\floyd" -> "floyd"
"AD\manny"   -> "manny" # perl escapes normal char, no harm

Thank you for all the help,
