Suppose I have a file that is comma delimited, but then certain fields contain multiple entries using a different delimiter ( in the example below the second delimiter of field 2 is a semi-colon). What perl one-liner at bash prompt would turn the following example data from 
ftsI,DB00303
HDC,DB00114; DB00117
F13A1,DB01839; DB02340; DB11311; DB13151

into 

ftsI,DB00303
HDC,DB00114
HDC,DB00117
F13A1,DB01839
F13A1,DB02340
F13A1,DB11311
F13A1,DB13151

The point of this is to go from a one to many mapping line by line, to a one to one mapping line by line ( at least with respect to the fields in question.

Something like the following is what I am looking for ... I know this syntax is wrong but hoping that it will get the conceptual point across....

cat file|cut-f1,10|perl -pe 'foreach $entry (@F[1]){print $F[0] . "\t" . $entry . "\n";}'
