I also recently had a need for printing multi-line "records" in which a
specified pattern appeared somewhere in the record.  The following
short csh script uses the awk capability to treat whole lines as fields
and empty lines as record separators to print all the records from
standard input that contain a line matching a regular specified as an
argument:

#!/bin/csh -f
awk 'BEGIN {RS = ""; FS = "\n"; OFS = "\n"; ORS = "\n\n"} /'"$1"'/ {print} '
