In addition to what Robin has already said, we also need a clear English description of what you are trying to do.

It looks like you want to ignore every line of input that does not have "C" as the first character on the line and then look at the remaining lines in groups of three. If the first line of a group is not literally Identifier "Findme" and the second line of a group is not literally Name "Positive" and the third line of a group is not literally AGT_AUTO then that group should also be ignored.

If that is what you're trying to do, I don't understand why producing that output would be important to anyone. It would seem that just knowing how many times a group matched each of those lines in sequence might be much more useful.

hosts.equiv(4)						     Kernel Interfaces Manual						    hosts.equiv(4)

NAME
hosts.equiv, .rhosts - security files authorizing access by remote hosts and users on local host DESCRIPTION
The file and files named found in users' home directories specify remote hosts and users that are "equivalent" to the local host or user. Users from equivalent remote hosts are permitted to access a local account using or or to to the local account without supplying a password (see rcp(1), remsh(1), and rlogin(1)). The security provided by is implemented by the library routine, (see rcmd(3N)). In this description, hostequiv means either the system file or the user file. Note that must be owned either by the root or by the user in whose home directory it is found and it must not be a symbolic link. The file defines system-wide equivalency, whereas a user's file defines equivalency between the local user and any remote users to whom the local user chooses to allow or deny access. An entry in the hostequiv file is a single line (no continuations) in the format: Thus, it can be: o A blank line. o A comment line, beginning with a o A host name, optionally followed by a comment. o A host name and user name, optionally followed by a comment. A host or user name is a string of printable characters, excluding whitespace, newlines, and Names are separated by whitespace. For a user to be granted access, both the remote host name and the user name must "match" an entry in hostequiv. When a request is made for access, the file is searched first. If a match is found, access is permitted. If no match is found, the file is searched, if one exists in the local user's home directory. If the local user is a superuser, is ignored. A host name or user name must match the corresponding field entry in hostequiv in one of the following ways: Literal match A host name in hostequiv can literally match the official host name (not an alias) of the remote host. A user name in hostequiv can literally match the remote user name. For a user name to have literal match in the file, the remote user name must literally match the local user name. Domain-extended match The remote host name to be compared with entries in hostequiv is typically the official host name returned by (see gethostent(3N)). In a domain-naming environment, this is a domain-qualified name. If a host name in hostequiv does not literally match the remote host name, the host name in hostequiv with the local domain name appended may match the remote host name. If the host name in hostequiv is of this form, and if name literally matches the remote host name or if name with the local domain name appended matches the remote host name, access is denied regardless of the user name. If the user name in hostequiv is of this form, and name literally matches the remote user name, access is denied. Even if access is denied in this way by access can still be allowed by Any remote host name matches the host name in hostequiv. Any remote user matches the user name netgroup_name is the name of a network group as defined in netgroup(4). If the host name in hostequiv is of this form, the remote host name (only) must match the specified network group according to the rules defined in net- group(4) in order for the host name to match. Similarly, if the user name in hostequiv is of this form, the remote user name (only) must match the speci- fied network group in order for the user name to match. netgroup_name is the name of a network group as defined in netgroup(4). If the host name in hostequiv is of this form, and if the remote host name (only) matches the specified network group according to the rules defined in netgroup(4), access is denied. Similarly, if the user name in hostequiv is of this form, and if the remote user name (only) matches the specified network group, access is denied. Even if access is denied in this way by access can still be allowed by EXAMPLES
