WHAT IT DOES
Read a chmod mode before it reaches a server.
Enter a Unix permission mode as octal digits or symbolic rwx text and see the individual owner, group, and other permissions, special bits, and the exact chmod command to run. The checkboxes and text form stay synchronized, so a mode such as 4755 is understandable before it is copied into a deployment script.
Why use it?
Use it to translate Unix permission notation into the access each class receives before copying a chmod command.
How to use this tool
- Enter an octal mode or nine-character permission string, or adjust the permission controls.
- For example, 644 means owner read/write and group/other read; it does not give anyone execute permission.
- Check the path and special bits before copying the command. The page changes no filesystem permissions, and the same bits have different practical consequences on files and directories.
Details and limitations
- Three-digit modes such as 644 and four-digit modes such as 4755 are accepted, including setuid, setgid, and sticky bits.
- Symbolic modes use the familiar nine-character form, including S and T when a special bit is set without execute permission.
- The command path is quoted locally so a filename containing spaces or a single quote is not silently changed.
- Common modes such as 000, 600, 644, 700, 755, 775, 777, 4755, 2755, 1777, and 6755 are represented directly by the calculator.
