Unix rwx string from a three-digit octal mode such as 755.
| rwx | – |
Use this calculator when a tutorial quotes 644 or 755 and you want the permission letters.
Each digit is 0–7. Read it as three decimal digits, not a single octal integer: 755 means owner 7, group 5, other 5. Bit 4 is r, bit 2 is w, bit 1 is x. 755 is rwxr-xr-x (owner all, group and other read+execute). Digits above 7 are invalid. ACLs, setuid, and the sticky bit are not shown.
Mode: Three octal digits, for example 644 or 755.
rwx: Owner, group, and other letters.
