Hi.

Except for some similar terms, this looks like a different problem.

You have 2 lists, essentially of tags, in increasing order, "E" followed by a decimal number, e.g. "E1", "E9" etc. The first list is a column in a file of other data, the second is a prefix to lines (some quite long).

You seem to want the tagged lines in the data file to be copied to STDOUT. Because both lists are in increasing order, this is basically a copy of tagged lines as selected by the first list, with the tag omitted, and with an empty line between them.

Does that describe the situation? ... cheers, drl
