After saying that I can suggest a few possibilities working with what you have.

1) If you want to search from a workstation through all the servers through SSH, firstly I suggest you configure a simple PKI infrastructure (private/public key). With that, you avoid typing the remote server password each time. In the client you need to have running a ssh-agent to login in behaf of your own user.

After thar you could use something like this:

for server in [ mumbai bangalore chennai delhi hyderabad other-hostnames ]; do echo $server; ssh $server zcat /path/to/voter.gz | grep -l "keyword"; done

You have to rewrite the above one-liner to your exact needs.


A quick work around for a better solution should be a script that parses that compressed files extracting all keywords and populating a MySQL (or any other) database. You're searches will be a lot faster and consistence because you have all the info in a single repository.

Ragards,
Leandro.
