What chmod 1777 means
1777 (rwxrwxrwt) is how /tmp is set up. Everyone can write, but the sticky bit (t) prevents users from
deleting or renaming each other's files. Use it for shared upload or scratch directories instead of plain 777.
Adjust the checkboxes above to see how a different mode compares, or go back to the chmod calculator.
