Good morning, I need an app or little software running on our Linux server that: • Add to File A the columns E and M of the file B. We have to start from the file file A column X and look for the corresponding values of the columns E and M of the file B. The output should be something like at the file C. We have to do this job only for the brand Ariete (Column U File A). • If in column M of File B there is 1. Alta we need to put a value in the column AA of the file C for example 15 2. Media always in the column AA of the file C we vale to put another value 3. Bassa always in the column AA of the file C we vale to put another value 4. Critica always in the column AA of the file C we vale to put another value We need to can change these values. For this reason these values are variables. • File C column AB = column Y + a value ( for example 0.6) • File C column AC = column AB + a value (%) (for example 4.5%) We only need 2 decimals. • File C column AD = column AC + a value (%) (for example 2.7%) We only need 2 decimals. + a value (for example 0.35) • File C column AE = column AC + column AD • File C column AF = column AE + a value (for example 12) • The output (File C) should be available in an FTP area of the server The imput and output files are attached. For any question do not hesitate to contact me. Thanks, Marco
