Learning Linux tips
🐧
Each digit is the sum of read (4) + write (2) + execute (1). So 7 = rwx, 5 = r-x, 6 = rw-. Toggle the boxes to see it click.
💡
The three digits are owner, group, other — in that order. 750 = owner full, group read+execute, other nothing.
🎯
Edit the octal field directly to reverse-engineer what a permission like 644 actually grants.
