1)Perl Script to obtain data file in a desired format
Category: Files/ Input/ Output
Level: Beginner
Description: This document discusses about using Perl, how we can obtain a data file in a particular desired format, given a data file in a random format. By format, we refer to the order of columns in the input data file. Using this Perl script, we obtain output data file in a particular format and we get another file having discarded data lines, based on some filtering condition. This will be useful, especially when we need data in a particular format in the data file, so as to store that data in database further. This is because once we obtain data file in a particular format, the logic/code for processing the data from data file for storing in database need not be changed every time. This Perl script takes care of converting input data file to a data file in a particular pre-defined format. Additionally, the records in the input data file can be filtered out based on some condition. For example, here we discard the lines if the number of fields in a line does not match the pre-defined number of fields. These discarded records can then be kept in another discard output data file.
Compatibility: 5.0 (all versions)
