STICKY(8) BSD System Manager's Manual STICKY(8) NAME sticky -- sticky text and append-only directories DESCRIPTION A special file mode, called the sticky bit (mode S_ISTXT), is used to in- dicate special treatment for directories. It is ignored for regular files. See chmod(2) or the file <sys/stat.h> for an explanation of file modes. STICKY DIRECTORIES A directory whose `sticky bit' is set becomes an append-only directory, or, more accurately, a directory in which the deletion of files is re- stricted. A file in a sticky directory may only be removed or renamed by a user if the user has write permission for the directory and the user is the owner of the file, the owner of the directory, or the super-user. This feature is usefully applied to directories such as /tmp which must be publicly writable but should deny users the license to arbitrarily delete or rename each others' files. Any user may create a sticky directory. See chmod(1) for details about modifying file modes. HISTORY A sticky command appeared in Version 32V AT&T UNIX. BUGS Neither open(2) nor mkdir(2) will create a file with the sticky bit set. BSD June 5, 1993 BSD
