A directory for +which the sticky bit is set restricts deletion of files it contains. A file in +a sticky directory can only be removed or renamed by a user who has write +permission on the directory, and either owns the file, owns the directory, has +write permission on the file, or is a privileged user. Setting the sticky bit +is useful for directories such as \fB/tmp\fR, which must be publicly writable +but should deny users permission to arbitrarily delete or rename the files of +others. +.sp +.LP +If the sticky bit is set on a regular file and no execute bits are set, the +system's page cache will not be used to hold the file's data. This bit is +normally set on swap files of diskless clients so that accesses to these files +do not flush more valuable data from the system's cache. Moreover, by default +such files are treated as swap files, whose inode modification times may not +necessarily be correctly recorded on permanent storage. +.sp +.LP +Any user may create a sticky directory. See \fBchmod\fR for details about +modifying file modes. +.SH SEE ALSO +.sp +.LP +\fBchmod\fR(1), \fBchmod\fR(2), \fBchown\fR(2), \fBmkdir\fR(2), +\fBrename\fR(2), \fBunlink\fR(2) +.SH BUGS +.sp +.LP +The \fBmkdir\fR(2) function will not create a directory with the sticky bit +set. |
