Hi all,

I have files with mailing addresses in them. There are normally 4-5 lines with
the first line starting with "address: " then the person's name and 3 or 4
more lines of address. Can (how) I use grep to pull all the address out? If
not grep what else?

I don't think grep can handle variable multiline results.

I would attack it with awk. (or gawk).

It is a pretty flexible reporting package.

Ignoring syntax a control file like:

START {print_lines=0; echo "File Header" > "output_file" }
/address:/ {print_lines=4}
{print_lines = print_lines-1
if (print_lines > 0) print $0 >> "output_file"
}

should be the basic code.

Then invoke it with:
awk -f control_file *

FYI: Double check all the above, but it should be enough to point you
in the right direction.
