What ID? What part of that characterstring is the ID? Is there more
than one?

Probably, but you are going to have to be clearer about what it is
that you are trying to do.
Also, as this is the comp.unix.programmer newsgroup, and not (say)
comp.unix.shell, you'll have to give us a clue as to what would be an
acceptable solution. Are you looking for a bash solution, or would awk
do? Is C acceptable, or do you want to do this in Perl?

Not until you explain what an ID is. Is it a number? Does it
include a "t"? Are there 4 of them on that line, or is there 1,
or is it some other number? Is it significant that there's a
comma at the end of the line, and does that mean that there
are actually 5 IDs on that line and that the last ID on the line
is the empty string?
