File list commands

File list commands

You can use a command to generate a list of source files for a mapping. You can use a valid DOS or UNIX command, batch file, or shell script.
Data Integration
reads each file in the list when the task runs.
Use a command to generate a file list when the list of source files changes often or when you want to generate a file list based on specific conditions. For example, you can use a command to generate a file list from all files in a directory or based on the file names.
Use the following guidelines when you generate a file list through a command:
  • You must enter Windows commands that use parameters such as "/b" in a batch file.
  • You must enter fully qualified file paths in each command, batch file, and shell script.
  • You cannot use an in-out parameter for the file list command.

UNIX Example with Shell Script

You need to extract data from parts lists that are stored on a Linux machine. The parts lists are text files that are stored in the
The following table shows the command that you enter in the Source transformation and the contents of the corresponding shell script:
Shell Script (
cd /home/dsmith/flatfile/parts ls *.txt

Windows Example with Batch File

You need to extract data from sales records that are stored on a Windows machine. The sales record files are stored in the
directory and use the naming convention
The following table shows the command that you enter in the Source transformation and the corresponding batch file contents:
Batch File (SalesSrc.bat)
@echo off cd C:\SalesRecords dir /b SalesRec_??-??-2017.txt

Example without Shell Script or Batch File

You can also generate a file list through a command instead of through a batch file or shell script. For example, the following command generates a file list that contains one file named source.csv:
echo C:\sources\source.csv
