Input:

user=alexander
registeredwebsite=yahoo.com

user=james
registeredwebsite=gmail.com
registeredwebsite=fb.com
registeredwebsite=google.com

user=kelly
registeredwebsite=gmail.com
registeredwebsite=fb.com
registeredwebsite=google.com

user=natasha

registeredwebsite=yahoo.com

user=bipasha
registeredwebsite=hotmail.com
registeredwebsite=medicus.com
registeredwebsite=yahoo.com

user=paul
registeredwebsite=yahoo.com

Need List of users registered only in yahoo.com website.

Need list of users registered not only yahoo but also other websites.

Output-2:

Mod Comment Surrounding your entire post with ICODE tags is not what is expected. Use CODE tags around sample input, around sample output, and around code segments.

With all of the help you got on your last request: Need help for count using shell, you must have a good start on a script to do this.

Show us what you have tried, show us the output it produces (both normal output and diagnostic messages).

Hi Don Cragun,

I tried below but it did't worked.
Code:
awk '/pattern/{nr[NR]; nr[NR+4]}; NR in nr' file

Mod Comment Please use CODE tags when displaying sample input, sample output, and non-HTML code segments.
Only use HTML tags when displaying HTML code segments.

Small variation:
Code:
awk -F= 'NF==4 && $4=="yahoo.com"{print $2}' RS= file

Code:
alexander
paul
mike

The condition for using RS= (set the RS variable to an empty string) is that the separation between segments must consist of two or more consecutive newlines, nothing else (no extra spaces).

--
Otherwise, try something like:
Code:
awk -F= '$1=="user"{if(n)print n; n=$2; next} NF && $2!="yahoo.com"{n=""} END{if(n)print n}' file

or:
Code:
awk -F= '$1=="user"{if(n)print n; n=$2; next} $1=="registeredwebsite" && $2!="yahoo.com"{n=""} END{if(n)print n}' file

Code:
users={}
mark=[]
with open("a.txt") as file:
	for line in file:
		line=line.replace("\n","")
		if len(line)==0:
			continue
		if 'user=' in line:
			user=line
		else:
			if user in users:
				users[user] += 1
			else:
				users[user] = 1
			if 'yahoo' in line:
				mark.append(user)
print("========not only yahoo=========")
for user in mark:
	if users[user]>1:
		print(user)

print("========yahoo=========")	
for i in mark:
	print(i)
