How to search using ssh on multiple hosts?

Hi guys - I am having a hard time trying to figure how to search for a certain string on config files hosted on multiple hosts.

This is an example:

Code:
Hostnames: myhost1.mycompany.com|myhost2.mycompany.com|myhost3.mycompany.com
 
String to search for: myipaddress.somehost.com
 
Directory structure (different in every host): /somedir/somedir/somedir

I understand that maybe I would need a script to solve this issue? as there are many hosts.

Any guidance would help.

NAME
hosts - The host name data base SYNOPSIS
/etc/hosts DESCRIPTION
The hosts file contains information regarding the known hosts on the network. For each host a single line should be present with the fol- lowing information: IP_address canonical_hostname aliases Items are separated by any number of blanks and/or tab characters. The # (number sign) indicates the beginning of a comment; characters up to the end of the line are not interpreted by routines which search the file. When using the name server named(8), this file provides a backup when the name server is not running. For the name server, it is suggested that only a few addresses be included in this file. These include address for the local interfaces that ifconfig(8) needs at boot time and a few machines on the local network. This file may be created from the official host data base maintained at the Network Information Control Center (NIC), though local changes may be required to bring it up to date regarding unofficial aliases and/or unknown hosts. As the data base maintained at NIC is incom- plete, use of the name server is recommend for sites on the DARPA Internet. Network addresses are specified in the conventional . notation using the inet_addr() routine from the Internet address manipulation library, inet_addr(3). Host names may contain any printable character other than a field delimiter, newline, or comment character. RELATED INFORMATION
Commands: ifconfig(8), named(8) Functions: gethostbyname(3) delim off hosts(4)
