How Permission Conversion Works

Linux file permissions can be represented in both octal (e.g., 644) and symbolic (e.g., rw-r--r--) notation. This tool lets you convert between the two instantly.

Octal Notation

Each digit represents permissions for owner, group, and others:

  • 4: read (r)
  • 2: write (w)
  • 1: execute (x)

Add the values for each user class. For example, 6 (4+2) means read and write (rw-).

Symbolic Notation

Symbolic notation uses r (read), w (write), and x (execute) for each of owner, group, and others. For example, rw-r--r-- means owner can read/write, group and others can only read.

Examples

  • 755 ↔ rwxr-xr-x
  • 644 ↔ rw-r--r--
  • 600 ↔ rw-------
