And, especially if you are trying to insert the quoted text in any place other than the start of the target file or the end of the target file, why is using echo a requirement?
Is this a homework assignment?
Are you trying to insert text you showed us in post #1 into some other file, or are you trying to insert some other text into the file you showed us in post #1?

oggdec(1) Vorbis Tools oggdec(1)
NAME
oggdec - simple decoder, Ogg Vorbis file to PCM audio file (Wave or RAW).
SYNOPSIS
oggdec [ -Qhv ] [ -b bits_per_sample ] [ -e endianness ] [ -R ] [ -s signedness ] [ -o outputfile ] file ...
DESCRIPTION
oggdec decodes Ogg Vorbis files into PCM-encoded ("uncompressed") audio files, either Wave or RAW format.
For each input file, oggdec writes to a filename based on the input filename, but with the extension changed to ".wav" or ".raw" as appro-
priate.
If the input file is specified as - , then oggdec will read from stdin, and write to stdout unless an output filename is specified. Like-
wise, an output filename of - will cause output to be to stdout.
Writing Wave format to stdout is a bad idea. Wave requires a seekable medium for the header to be rewritten after all the data is written
out; stdout is not seekable.
OPTIONS
-Q, --quiet
Suppresses program output.
-h, --help
Print help message.
-V, --version
Display version information.
-b n, --bits=n
Bits per sample. Valid values are 8 or 16.
-e n, --endian=n
Set endianness for 16-bit output. 0 (default) is little-endian (Intel byte order). 1 is big-endian (sane byte order).
-R, --raw
Output in raw format. If not specified, writes Wave file (RIFF headers).
-s n, --sign=n
Set signedness for output. 0 for unsigned, 1 (default) for signed.
-o filename, --output=filename
Write output to specified filename. This option is only valid if one input [file] is specified, or if raw mode is used.
EXAMPLES
Decode a file enabler.ogg to enabler.wav
as little-endian unsigned 16-bit (default options):
oggdec enabler.ogg
Decode a file enabler.ogg to enabler.raw as headerless little-endian unsigned 16-bit:
oggdec --raw=1 enabler.ogg
Decode enabler.ogg to enabler.crazymonkey as unsigned 8-bit:
oggdec -b 8 -s 0 -o enabler.crazymonkey enabler.ogg
Decode enabler.ogg to enabler.raw as big-endian signed 16-bit (any of the following):
oggdec -R -e 1 -b 16 enabler.ogg
oggdec -R -e 1 -b 16 -o enabler.raw - < enabler.ogg
oggdec -R -e 1 -b 16 - < enabler.ogg > enabler.raw
Mass decoding (foo.ogg to foo.wav, bar.ogg to bar.wav, quux.ogg to quux.wav, etc.):
oggdec *.ogg
