jdbc2csv.jar
Command-line sql JDBC tool
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'. -

aws-cli
Universal Command Line Interface for Amazon Web Services
The AWS CLI is the universal command-line interface for managing AWS services, automating tasks, and scripting cloud workflows. It exposes nearly every public API from EC2 and S3 to IAM, Lambda, and beyond, providing parity with the service SDKs in a tool you can run anywhere. Profiles, regions, single-sign-on, and credential helpers make it straightforward to switch contexts securely across accounts and environments. Its output controls and JMESPath querying let you slice, filter, and transform JSON responses directly in the shell, which is essential for automation. Waiters, paginators, and retries handle long-running or large list operations cleanly so scripts are resilient. The CLI’s stability and extensive documentation make it a cornerstone for CI/CD, incident response, and day-to-day operations. -

Live CD With Zerofree Utility i686 32Bit
A Custom Puppy Linux Live CD With Zerofree Utility i686 32 Bit
After Booting with this Live CD, just click on the CDROM icon on the Desktop, to open its folder contents, then Right Click the zerofree.sh file and Choose the "Run in Terminal" option and then follow the instructions shown on the terminal. As you may be aware, Booting with a Live CD, requires that you need to change the Boot Order on your System / Guest BIOS, quickly on startup, by pressing either F2 OR F12 OR F10 OR an equivalent key and then change the Boot Order to boot from the CDROM first. Some Hints: Puppy Linux Live CDs show some dialogs / settings window on first startup / first shutdown. Feel free to dismiss / close them, if you do not want to make any changes, to the live cd's operation, next time, on the same system. This will not affect the zerofree's work in any way. Apart from this, using the Internet Browser, built in, would require a Free Memory of 1 GB or more, for better Performance ( as it is generally a memory intensive activity ) -

EnDiskEx
Bulk extractor for Ensoniq-formatted disk images
EnDiskEx is a command-line tool that bulk extracts instruments, sequences, songs, and banks from Ensoniq-formatted disk images (RAW, GKH, EDE, and EDA) for the EPS/ASR family of samplers. The extracted files are saved as EFE / SMF / TXT files. EnDiskEx is designed to extract Ensoniq banks for re-creation within a different DAW. It will track down the instrument and song files from bank references even if they were saved on another disk. There also exists a disk mapping feature to correct for any errors in this process caused by having relabeled disks, forgotten to label disks, etc. EnDiskEx has been tested and validated against a variety of RAW, GKH, EDE, and EDA images files the dev team has, including but not limited to, the ASR factory disks, the EPS 16+ factory disks, and the EPS (classic) factory disks. -
