Open Source Java Command Line Tools

jdbc2csv is a small command-line tool written in JAVA and can be used on all platforms, for which JRE 8 or higher is available. To connect to a specific DBMS the tool uses its JDBC driver. The result of the executed 'select' query is displayed in CSV format ( different standards are supported ). When there is an error the tool stops with exit code 1 and the error message is output on stderr. jdbc2csv is created with a main purpose to be used in shell-scripts. Relatively easy to configurate, this tool is suitable for queries ‘select’, ‘update’ and ‘delete’. I think that is not suitable for a large number of requests, like 'insert'.

IMG2GSLIB is a small command line tool that converts images to grids into GEO-EAS format readable by geoscientific software such as GSLIB, SGeMS, Isatis, Gocad, Petrel, etc. It now can output 3D volumes from image stacking.

CSV Comparator is a tool for comparing files which contain CSV-Data. It was created for performance engineers to be able to have a easy way to compare data from two testruns and be able to automate the comparing process of various files with scripts. There is a command line tool as well as a user interface. In case you need to compare .xml-Files you can convert them to .csv-Files with my other project CSV Transformer. The advantages by using CSV as input and output are the following: - Many applications allow an export of its data to CSV or Excel(were it could be saved to CSV) - It is possible to pre- and postprocess the data, e.g removing version numbers before comparing - It is easy to create CSV data from logfiles and other resources by using unix tools like sed or awk - CSV can be loaded into other applications, especially Excel, were it can be formatted by macros for analyzing.
