I have Linux machine red-hat 5.1 and I ask the following question
my target is to create new output_file.txt file from answer_file.txt according to data_file.txt
as we see here I run first the data_file.txt and export all parameters from the file then I try to print all answer_file.txt in to new file output_file.txt
so I will get this file with the new parameters from data_file.txt but I not success -:(
please advice how to export the parameters from data_file.txt in to answer_file.txt and then create new file with the correct values?
remark - I work with bash and I not want to use sed or awk for this task , and I not want to change the content of the original data_file.txt or answer_file.txt ( I need the simple way from bash shell to do the Job )
