I'm trying to redirect awk's output to a BASH variable. Currently the statement looks like this
options=`awk '{ while (i < NF) { print $i; ++i } }' answer

tftp
tftp(1) User Commands tftp(1)NAME
tftp - trivial file transfer program
SYNOPSIS
tftp [ host [port]]
DESCRIPTION
tftp is the user interface to the Internet TFTP (Trivial File Transfer Protocol), which allows users to transfer files to and from a remote
machine. The remote host and optional port may be specified on the command line, in which case tftp uses host as the default host, and if
specified, port as the default port, for future transfers. See the connect command below.
USAGE
Once tftp is running, it issues the prompt tftp> and recognizes the following commands:
Commands
connect host-name [ port ]
Set the host, and optionally port, for transfers. The TFTP protocol, unlike the FTP protocol, does not maintain connections between
transfers; thus, the connect command does not actually create a connection, but merely remembers what host is to be used for transfers.
You do not have to use the connect command; the remote host can be specified as part of the get or put commands.
mode transfer-mode
Set the mode for transfers; transfer-mode may be one of ascii or binary. The default is ascii.
put filename
put localfile remotefile
put filename1 filename2 ... filenameN remote-directory
Transfer a file, or a set of files, to the specified remote file or directory. The destination can be in one of two forms: a filename
on the remote host if the host has already been specified, or a string of the form:
host:filename
to specify both a host and filename at the same time. If the latter form is used, the specified host becomes the default for future
transfers. If the remote-directory form is used, the remote host is assumed to be running the UNIX system.
The host can be a host name (see hosts(4) or ipnodes(4)) or an IPv4 or IPv6 address string (see inet(7P) or inet6(7P)). Since IPv6
addresses already contain ":"s, the host should be enclosed in square brackets when an IPv6 address is used. Otherwise, the first
occurrence of a colon will be interpreted as the separator between the host and the filename. For example,
[1080::8:800:200c:417A]:myfile
Files may be written only if they already exist and are publicly writable. See in.tftpd(1M).
get filename
get remotename localname
get filename1 filename2 filename3 ... filenameN
Get a file or set of files (three or more) from the specified remote sources. source can be in one of two forms: a filename on the
remote host if the host has already been specified, or a string of the form:
host:filename
to specify both a host and filename at the same time. If the latter form is used, the last host specified becomes the default for
future transfers. See the put command regarding specifying a host.
quit
Exit tftp. An EOF also exits.
verbose
Toggle verbose mode.
trace
Toggle packet tracing.
status
Show current status.
rexmt retransmission-timeout
Set the per-packet retransmission timeout, in seconds.
timeout total-transmission-timeout
Set the total transmission timeout, in seconds.
ascii
Shorthand for mode ascii.
binary
Shorthand for mode binary.
blksize transfer-blocksize
The value of the transfer blocksize option to negotiate with the server. A value of 0 disables the negotiation of this option.
srexmt server-retransmission-timeout
The value of the retransmission timeout option to request that the server uses. A value of 0 disables the negotiation of this option.
tsize
A toggle that sends the transfer size option to the server. By default, the option is not sent. The transfer size option is not sent
with a write request when the transfer-mode is ascii.

NOTES
The default transfer-mode is ascii. This differs from pre-SunOS 4.0 and pre-4.3BSD systems, so explicit action must be taken when transfer-
ring non-ASCII binary files such as executable commands.
Because there is no user-login or validation within the TFTP protocol, many remote sites restrict file access in various ways. Approved
methods for file access are specific to each site, and therefore cannot be documented here.
When using the get command to transfer multiple files from a remote host, three or more files must be specified. If two files are speci-
fied, the second file is used as a local file.
