Question Not working for me :-(

Hello malcomex999, Vi-Curious,

Thanks for the replies.I tried both the suggestions but none of them worked for me :-(. My file contains -

~/Desktop$ cat b.txt
hello hello hello hello
good morning
good evening

I am trying to search for hello string in this file and am expecting it to print 'hello' only twice in the output. Please let me know if i am doing something wrong there.

~/Desktop$ awk -v var="hello" '{str=$0;cnt=gsub(var,arr);if(cnt==2)print str}' b.txt
<No OutPut here>

~/Desktop$ perl -nle '{print $_ if scalar(@_ == $_ =~ /hello/g) == 2}' b.txt
<No OutPut here>

Regards.
