I have some large login files that I need to extract (user)@(server) from. Where it gets tricky is that there is usually more than one '@' sign on each line(although it does have a leading space if it's not part of the (user)@(server) string), I need only the (user)@(server) section, I need only unique occurrences, AND I need to drop the ones where the (server) is an IP address. Here are a few sample lines from the file:
The output I would need the command to generate from these lines would be:
Can it be done?

Hi,
I'm in the midst of writing a UNIX script that sftp's files to an external host and am stuck with a problem. The problem is that the files created on my server as a order number that correlates to a sequence of directories on the remote host which is where the file should be ftp'ed.

vos_listaddrs
VOS_LISTADDRS(1) AFS Command Reference VOS_LISTADDRS(1)NAME
vos_listaddrs - Displays all VLDB server entries
SYNOPSIS
vos listaddrs [-uuid <uuid of server>]
[-host <address of host>] [-printuuid]
[-cell <cell name>] [-noauth] [-localauth]
[-verbose] [-encrypt] [-noresolve] [-help]
vos lista [-u <uuid of server>] >>>
[-h <address of host>] [-p]
[-c <cell name>] [-noa] [-l]
[-v] [-e] [-nor] [-he]
DESCRIPTION
The vos listaddrs command displays all of the server entries from the Volume Location Database (VLDB). An entry is created as the File
Server initializes and registers the contents of its /var/lib/openafs/local/sysid file in the VLDB.
OPTIONS -host <address of host>
Rather than displaying all the server entries, display only server entries for the specified host. This will show all multihomed
addresses registered by that File Server in the VLDB.
-uuid <uuid of server>
Rather than displaying all the server entries, display only server entries for the File Server with the specified UUID. This will show
all multihomed addresses registered by that File Server in the VLDB and also allows mapping a File Server UUID to its address.
-printuuid
Prints the UUID of server entries in addition to the registered addresses. The -printuuid option is available in OpenAFS versions 1.4.5
or later and 1.5.8 or later.
-cell <cell name>
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see vos(1).
-noauth
Assigns the unprivileged identity anonymous to the issuer. Do not combine this flag with the -localauth flag. For more details, see
vos(1).
-localauth
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The vos command interpreter presents it to the
Volume Server and Volume Location Server during mutual authentication. Do not combine this flag with the -cell argument or -noauth
flag. For more details, see vos(1).
-verbose
Produces on the standard output stream a detailed trace of the command's execution. If this argument is omitted, only warnings and
error messages appear.
-encrypt
Encrypts the command so that the operation's results are not transmitted across the network in clear text. This option is available in
OpenAFS versions 1.4.11 or later and 1.5.60 or later.
-noresolve
Shows all servers as IP addresses instead of the DNS name. This is very useful when the server address is registered as 127.0.0.1 or
when dealing with multi-homed servers. This option is available in OpenAFS versions 1.4.8 or later and 1.5.35 or later.
-help
Prints the online help for this command. All other valid options are ignored.
OUTPUT
The output displays all server entries from the VLDB, each on its own line. If a file server machine is multihomed, all of its registered
addresses appear on the line. The first one is the one reported as a volume's site in the output from the vos examine and vos listvldb
commands.
The VLDB records IP addresses, and the command interpreter has the local name service (either a process like the Domain Name Service or a
local host table) translate them to hostnames before displaying them. If an IP address appears in the output, it is not possible to
translate it.
The existence of an entry does not necessarily indicate that the machine that is still an active file server machine. To remove obsolete
server entries, use the vos changeaddr command with the -remove argument.
EXAMPLES
The following command displays the VLDB server entries in the ABC Corporation cell:
% vos listaddrs
sv5.abc.com
sv1.abc.com
sv2.abc.com afs2.abc.com
sv6.abc.com
The following command displays the VLDB server entry and UUID for host sv5.abc.com in the ABC Corporation cell:
% vos listaddrs -p -ho sv5.abc.com
UUID: 000c5aff-8246-1699-96-c4-437b5a45aa77
sv5.abc.com
PRIVILEGE REQUIRED
None
