using Grep for only a certain number of columns
I am given a file with a list of names for the first 20 characters. The 20 characters after is a list of names that somebody is supposed to team up with.

Now i'm trying to write a simple script that will read a name somebody inputs and then looks only in the first 20 characters.

For example. (Due to the nature of BBS posting length of columns are not given, the first name is the desired target for searching, the second name is the person teamed up with the first.

John Bow : Lucy Hemmings
Bob Billy : Bibliotheque Frenchness
Lucy Hemmings : John Bow

if somebody inputs John, I would get both Lucy and John, and this is not what I want. Any ideas?

I am considering piping grep -w with something else as it seems to at least cut out all the names which have no relevance.

UNAFS(8)                                                      System Manager's Manual                                                     UNAFS(8)

NAME

       unafs - script to warn users about their weak passwords

SYNOPSIS

       unafs password-files cell-name

DESCRIPTION

       This  manual  page  documents  briefly  the  unafs command, which is part of the john package.  This manual page was written for the Debian
       GNU/Linux distribution because the original program does not have a manual page.  john, better known as John the Ripper, is a tool to  find
       weak passwords of users in a server.
       The unafs tool gets password hashes out of the binary AFS database, and produces a file usable by John.

SEE ALSO

       john(8), mailer(8), unique(8), unshadow(8).

       The programs are documented fully by John's documentation, which should be available in /usr/share/doc/john or other location, depending on
       your system.

AUTHOR

       This manual page was written by Jordi Mallach <jordi@debian.org>, for the Debian GNU/Linux system (but may be used by others).
       John the Ripper and mailer were written by Solar Designer <solar@openwall.com>. The complete list of contributors can be found in the CRED-
       ITS file in the documentation directory.
