csh,ksh or sh

$cat stat_demo.awk
#start here
BEGIN{
FS=":"
#seperator is set to :
}
{
#$7, is 7 field in passwd file
stat_array[$7]=stat_array[$7]+1;
}
END{
print "Login-Shell Count" ;
for (i in stat_array) print i, stat_array[i]
#Displays statistics
}
#end here


To use this , Just say

awk -f stat_demo.awk /etc/passwd
