This is interesting... You have shown us six lines of output from a command that should produce no more than four lines of output.

And, you say you want to process a file named input.txt, but the code that follows never reads that file. Instead, it reads two other files named project.txt and projection.txt. And, with default fields separators, awk will see only one field in each of the above lines; but your code below is using awk to extract the 3rd field from the 1st line of the file named projection.txt. Does the 1st line in project.txt have a different format than the lines you have shown us above in input.txt? If so, please show us the first few lines of input.txt instead of the last few lines.

Does the echo in your script print the value of $week that you were hoping to get? (If not; what does it print and what did you want it to print?)

You code reads from projection.txt and project.txt and produces the files prom.txt, adus.txt, none.txt, and pro.txt.

What is the relationship between the input.txt you showed us above and the projection.txt, and project.txt files read by your script?

When your script exits, which of the files it produces are needed for something else; and which are just temporary files only needed within the above script?
