STICKY FILES

  STICKY FILES

STICKY FILES
       On  older  Unix  systems,  the sticky bit caused executable files to be
       hoarded in swap space.  This feature is not useful on  modern  VM  sys-
       tems, and the Linux kernel ignores the sticky bit on files.  Other ker-
       nels may use the sticky bit on files for system-defined  purposes.   On
       some systems, only the superuser can set the sticky bit on files.

STICKY DIRECTORIES
       When  the sticky bit is set on a directory, files in that directory may
       be unlinked or renamed only by root or their owner.  Without the sticky
       bit,  anyone able to write to the directory can delete or rename files.
       The sticky bit is commonly found on directories, such as /tmp, that are
       world-writable.

在man chmod中找到了一些关于关于粘着位的介绍。粘着位对于服务器的权限设定比较有用，我记得在samba的配置中，就用到了粘着位。
