Formatting data in a raw file by using another mapping file
Hi All,
i have a requirement where i need to format the input RAW file ( which is CSV) by using another mapping file(also CSV file). basically i am getting feed file with dynamic headers by using mapping file (in that target field is mapped with source filed) i have to convert the raw file into a standard format (target format).
currently i am using ETL tool to achieve this but it's taking long time.
i am trying to write generic shell script for this. could anyone help me in a high level view. i am new to scripting. the target file also be a CSV file.
thanks in advance
Ravi
