This product has charges associated with it for seller-performed integration of ncdu 1.22 with CentOS Stream 9, preparation of the ncurses disk-usage analyzer and runtime dependencies, application of a verified operating-system hardening baseline, and final AMI testing on a documented EC2 baseline.
This product provides ncdu 1.22 integrated with CentOS Stream 9 and delivered as an Amazon Machine Image (AMI) by ThinkCloud. The image includes the ncurses disk-usage analyzer and applies a verified operating-system hardening baseline for immediate deployment.
CentOS Stream 9 provides a stable foundation for system administration tools. ncdu (NCurses Disk Usage) helps administrators find space usage on remote servers without a graphical environment. Its interactive ncurses interface lets users navigate directories and inspect file and directory usage in POSIX-like environments.
Marketplace software charges cover seller-performed software and operating-system integration, preparation of ncdu and its runtime dependencies, application of the verified hardening baseline, repeatable image construction, and final AMI testing. Support and maintenance are supplementary services and are not the sole basis for the software charges.

AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
Pricing is based on actual usage, with charges varying according to how much you consume. Subscriptions have no end date and may be canceled any time.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
If you are an AWS Free Tier customer with a free plan, you are eligible to subscribe to this offer. You can use free credits to cover the cost of eligible AWS infrastructure. See AWS Free Tier for more details. If you created an AWS account before July 15th, 2025, and qualify for the Legacy AWS Free Tier, Amazon EC2 charges for Micro instances are free for up to 750 hours per month. See Legacy AWS Free Tier for more details.
You pay by the hour for ncdu running on CentOS Stream 9, with vendor support included. Pricing is usage-based, so you are billed only for the hours each instance runs. Each dimension maps to a specific AWS EC2 instance type, and the hourly rate follows the size and family you choose. Smaller instances cost less per hour, while larger compute, memory, storage, and accelerated instances cost more. You select the instance type that fits your workload's CPU, memory, and storage needs. There is no upfront commitment, and you can scale by picking different instance types.
Top-of-mind questions for buyers
What does one hourly unit cover on this listing?
Each unit is one running EC2 instance of the type you select, billed per hour. The rate bundles the ncdu software on CentOS Stream 9 plus vendor support. You pay for each hour an instance runs, counted separately for every instance you launch.
Am I charged when an instance is stopped or paused?
The software charge meters running hours only. A fully stopped instance does not accrue the hourly software fee. Underlying AWS storage or other AWS resources may still bill separately, but the ncdu software rate applies to running time.
How do I control cost when moving between instance types?
Your bill follows the instance type you choose at any given time. Switching to a different family or size changes the hourly rate for the hours that type runs. There is no upfront commitment, so you scale up or down by launching or stopping instance types as needed.

An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

Usage instructions
Connection Method
Connect via SSH as user 'ec2-user' to the running instance.
Use sudo to run commands requiring root access, or switch to root using: sudo su - root
Service Management
Note: ncdu is a standalone Command Line Utility, not a background service daemon. You do not need to "start" or "enable" it using systemctl.
How to use:
To scan the current directory: ncdu
To scan the entire root filesystem: sudo ncdu /
To exit the interface: Press 'q'
Network Configuration
Default Behavior: ncdu operates locally on the file system and does not open any network ports or sockets.
External Access: N/A. The tool is accessed exclusively via your SSH session.
AWS Security Groups: No specific ports need to be opened for ncdu itself. Only SSH port 22 is required for access.
Please allow SSH port 22 limited IPs for access.
