Top Forums Shell Programming and Scripting Find and select complete paragraph Post 302961972 by Don Cragun on Monday 7th of December 2015 04:40:36 AM

Given that you have asked us for help 61 times before with some of your problems being very similar to this one, it is disappointing that you are unable to guess that awk would be a good way to solve a problem like this and show us a start to a solution to this on your own.

You might try something like:
Code:
awk '
$0 == "== :: ==" {
	if(perm) {
		if(!pc++)
			print
		for(i = 1; i <= lc; i++)
			print l[i]
		print
		perm = 0
	}
	lc = 0
	next
}
{	l[++lc] = $0
	if($0 == "Nature: Permanent")
		perm = 1
}' april_2015.txt

As always, if you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk.
