help me do grep

[Jonathan I. Kamens]

You could do something like this:

#!/bin/sh

if [ $# -ne 2 ]; then
	echo "Usage: $0 pattern filename"
	exit 1
fi

AWK='BEGIN { doprint = 0
	record = ""
}
/\/\/\// { if (doprint) { printf("%s", record) }
	record = ""
	doprint = 0
	next
}
/'$1'/ { doprint = 1 }
{ record = record $0 "\n" }'

awk "$AWK" $2

If you only want to compare your pattern to a certain line of the entry, then
you can count entry lines as you go along and only set doprint to true if the
pattern matches *and* the current line number is the line of the entry against
which you want to compare.
