Searching part of a file

I was wondering if anyone knows where i could
find a script, or knows the procedure that would allow
me to search parts of *one* file for string. I.e. We have a list of names with an email address and would like to be able to have an engine search inside the file for the names instead of searching for a file with the names.. Thanks in advance :)

Assuming your file is of the form

email@somewhere.com,fred bloggs

then you can search it with a perl script similar to:-

open (FID, "filename.txt");
while (<FID>) {
  chop;
  ($email, $name) = split(/,/, $_);
  if ($name eq $theNameIAmLookingFor) {
    print "The email you want is $email\n";
  }
}
close(FID);

Alternatively if it is a Unix host you could use a grep program.
