If I understand correctly, you can pipe your output to: `awk '{a=$1} {if
(a > 3)   print a}''. `a' is awk variable. `$1' is first column of awk
input so you probably need to change it.

Thank you for your message . Yes , you are right . I really need to filter out that CallId with number of occurances say less than three. But your command is not getting through on my centos . Please correct me.

So, read `man awk', `man sed' etc, as John R. Dennison wrote. Also perl would be excelent for this kind of stuff.
