substitution of variable in template
I am a beginner programmer. I have a file that I am able to read through and place the data into variables using the read command. The data is then set to another variable and all the data in that variable resembles the file that I was able to read through, however when I use the sed -e "s/DATA/${data}/" template > newfile name, I can't substitute the data below into the ${data} variable.

Does any one have any ideas what we could do

nvram
nvram(8) System Manager's Manual nvram(8)
NAME
nvram - manipulate Open Firmware NVRAM variables
SYNOPSIS
nvram [ -p ] [ -f filename ] [ name ] [= value ] ...
DESCRIPTION
The nvram command allows manipulation of Open Firmware NVRAM variables. It can be used to get or set a variable. It can also be used to
print all of the variables or set a list of variables from a file. Changes to NVRAM variables are only saved by clean restart or shutdown.
In principle, name can be any string. In practice, not all strings will be accepted. New World machines can create new variables as
desired. Some variables require administrator privilege to get or set.
The given value must match the data type required for name. Binary data can be set using the %xx notation, where xx is the hex value of
the byte. The type for new variables is always binary data.
OPTIONS
-p Print all of the Open Firmware variables.
-f filename
Set Open Firmware variables from a text file. The file must be a list name=value statements. If the last character of a line is ,
the value will be continued to the next line.
EXAMPLES
example% nvram boot-args="-s rd=*hd:10"
Set the boot-args variable to "-s rd=*hd:10". This would specify single user mode with the root device in hard drive partition 10.
example% nvram my-variable="String One%00String Two%00%00"
Create a new variable, my-variable, containing a list of two C-strings that is terminated by a NUL.
