Help with AWK Script
Hello everybody,
Can someone please help me resolve this problem? I’m in my trial period and my employer has given me a task to test me and I still haven’t found the solution for my problem.
I have a csv file named masterFile1 that contains the following columns. Each line contains a computer’s properties (the file may contain more than 3 computers(Lines)). For example:
a,b,c,d,e,cpu_numb,cpu_core,cpu_model
a1,b1,c1,d1,e1,1,4,model1
a2,b2,c2,d2,e2,2,4,model1
a3,b3,c3,d3,e3,4,16,model45
...
...
The file may contain more than 3 lines (these lines are just examples).
I want a script that allows me to have an output file named masterFile2 for example that contains the following columns :
a,cpu_id,cpu_core,cpu_model
a1,1,4,model1
a2,1,2,model17
a2,2,2,model17
a3,1,4,model45
a3,2,4,model45
a3,3,4,model45
a3,4,4,model45
I want to delete the columns b,c,d,e,cpu_numb (the number of cpu in the computer) and add a new columns cpu_id that contains an ID for the cpu. For example, if we had a computer with the following datas
a,b,c,d,e,cpu_numb,cpu_core,cpu model
a2,b2,c2,d2,e2,2,4,model1
We have here 2 cpu and 4 core cpu (2 core cpu for each cpu)
The output file will contain the following columns with two lines this time because we have 2 cpu
a,cpu_id,cpu_core,cpu_model
a2,1,2,model1
a2,2,2,model1
Each Line will have a cpu_id (example: 2 linesà2 cpu_id (2 cpu); 4 lines à4cpu_id (4 cpu).
The cpu_core will contain 2 not 4 because now we have datas for each cpu.
Another example:
Input File:
a,b,c,d,e,cpu_numb,cpu_core,cpu model
a3,b3,c3,d3,e3,4,16,model45
We have 4 cpu with 16 cpu_core (4 cpu_core for each cpu) so we’ll have 4 cpu_id (4 lines)
Output File:
a,cpu_id,cpu_core,cpu_model
a3,1,4,model45
a3,2,4,model45
a3,3,4,model45
a3,4,4,model45
The input File contains an unknown number of lines
a,b,c,d,e,cpu_numb,cpu_core,cpu model
a1,b1,c1,d1,e1,1,4,model1
a2,b2,c2,d2,e2,2,4,model17
a3,b3,c3,d3,e3,4,16,model45
...
...
...
And the output File will contain
a,cpu_id,cpu_core,cpu_model
a1,1,4,model1
a2,1,2,model17
a2,2,2,model17
a3,1,4,model45
a3,2,4,model45
a3,3,4,model45
a3,4,4,model45
...
...

Thank you very much in advance. You will save my life.
