Set Sticky Bit on World Writable Directories

高レベル 1手動レビューsolaris

説明

When the so-called sticky bit (set with chmod +t) is set on a directory, then only the owner of a file may remove that file from the directory (as opposed to the usual behavior where anybody with write access to that directory may remove the file). Files in directories that have had the 'sticky bit' set, can only be deleted by users that have both write permissions for the directory in which the file resides, as well as ownership of the file or directory, or has sufficient privilege.
