Convert chmod numbers and rwx permissions.
Free Online Unix Permissions Calculator
The eko24.net Unix Permissions Calculator is a browser-based utility designed to make a specific development task faster and easier to inspect. It works directly from the page, so you can use it for quick coding, testing and troubleshooting without installing a separate desktop application or creating an account.
What does this tool do?
Unix file permissions describe read, write and execute access for the owner, group and others. Numeric chmod values such as 755 map to rwx permission combinations.
How to use Unix Permissions Calculator
- Enter, paste or configure the source information required by the tool.
- Choose the available action or settings for the result you need.
- Review the generated output or preview carefully.
- Copy the result and test it in the environment where you plan to use it.
When is it useful?
This tool can help with Linux servers, web hosting, shell scripts, deployment checks and file-access troubleshooting. It is intended for fast everyday development work where seeing a clean result immediately can save time compared with preparing the same output manually.
Practical tip
Choose or enter the permission values and compare the numeric chmod form with the symbolic rwx form before applying permissions on a server.
Privacy and local processing
Where the tool can perform its task with browser features alone, the input is handled directly in your browser. Tools that need to inspect a public URL may depend on the remote website and browser access rules. Avoid pasting secrets, private credentials or sensitive production data into any online utility unless you have confirmed that the workflow is appropriate for that information.
