Hi All, Thanks for the responses, Don , Rudi C, all thanks,

Rudi C, yes that is the only Snippet .., and I went ahead and got this.. ,

count.awk
Code:
{if(substr($1,7,1)=="p"){p++}}END{print "p_hosts = "p}
{if(substr($1,7,1)=="d"){d++}}END{print "d_hosts = "d}
{if(substr($1,7,1)=="o"){o++}}END{print "o_hosts = "o}
{if(substr($1,7,1)=="m"){m++}}END{print "m_hosts = "m}
{if((substr($1,7,1)!~"p") && (substr($1,7,1)!~"d") &&  (substr($1,7,1)!~"o") &&  (substr($1,7,1)!~"m")  ){n++}}END{print "Non_p_d_o_m_hosts = "n+0}


Execution:
Code:
$ awk -f count.awk datafile 
p_hosts = 17
d_hosts = 1
o_hosts = 1
m_hosts = 8
Non_p_d_o_m_hosts = 0

generated the counts now of the pattern..., Thanks all,

Code:
awk '
{$0 ~ /^......[dpom]/ ? a[substr($0, 7, 1)]++ : x++}
END {for (i in a) print i "_hosts = " a[i]; print "Non_p_d_o_m_hosts = " x++} ' infile

Quicky on the command line:
Code:
cut -c7 file | sort | uniq -c

Code:
   1 d
   8 m
   1 o
  17 p
