Question

This is a UNIX shell scripting question.

Consider the files files l2b1.iva, l2b2.iva, and l2b3.iva from your lab2B. These are raw performance data collected on a solar photovoltaic module installed at ASU Polytechnic campus. These data must be processed to determine the performance output of the system or panel. The 3 files correspond to 3 repeated measurements.

Upon processing, the test data are presented as shown in the table below:

The data in the table above are average values from 3 repeated measurements on panel id gge001. The 3 measurements gge001x, gge001y, and gge001z are shown in the table/file below.

For this lab, we’ll use the file below, obtained from previous labs.

You are to write a script that produces the “Performance Data” table as shown above.

Note the corresponding rows:

PLEASE answer SPECIFICALLY in UNIX Shell Script. Do NOT answer in Java/programming language code or UNIX shell commands.

done < $file

Description

Step 1 : Read all three files line by line at a time and concate string and store into one another file say file4.txt

i.e. file 1 line 1 - Date 23/12/2006 , file2 line 1 - Date 24/12/2016, file3 line 1 - Date 25/12.2006

in this case file4.txt contains 6 columns - Date 23/12/2006 Date 24/12/2016 Date 25/12.2006

Step 2 : using cut command we use the column 1 , 2, 4, 6 as per the desired result

in our case cut command result would be -   Date 23/12/2006 24/12/2016 25/12.2006

Step 3 : Now we need to replace Date from 'D' character using below command

${s1/Date/$stringalies1}

Now out output would be stored in output.txt

D 23/12/2006 24/12/2016 25/12.2006
