permissions in "rwx"-format
permissions as octal number

The file access permissions as shown by the UNIX command "ls -l" are given in the "rwx-format". With the command "chmod" you can write the permissions in octal format.

Usage: You may indicate the file access permissions with the checkboxes. After every change the rwx-format and the octal format are calculated. Or you type either a rwx-format or an octal format. After a mouseclick on any free space of the window the other format is calculated and the checkboxes are changed.

Example: What are the access permissions of a file that are given by "754" in octal format ? Type "754" into the field for octal formats. Click on any free space of the window and read the results in the other fields (rwx-format: rwxr-xr--, therefore the owner may read, write and execute the file, a group member may read and execute it and all others may just read it).

Remarks:
- Parts of this calculator have been copied from SelfHtml.
- Large and small numbers are written exponentially. As example 2.3e5 = 2.3⋅105 = 230000 or 4.5e-5 = 4.5⋅10-5 = 0.000045.
