I can deal with the duplicates, not that big of a deal, but I think I need help with my regex, some of the stings have a null value, and some have a value, I need the ones that look like this:

authDataAlias="cell-tstc-65_DM/userQ"

I'm only concerned with: cell-tstc-65_DM/userQ

If I do this, sed returns a blank line in the file since one of the authDataAlias strings is set to ="":

($line =~ m/authDataAlias=\"([^\"]*)\"/i)

cell-tstc-65_DM/userQ

cell-tstc-65_DM/user1

If I run this sed command, it ignores the empty sting, but returns too much of the line:

($line =~ m/authDataAlias=(.*-.*-.*_DM\/.*)/i)
