FBTAB(5)                    BSD File Formats Manual                   FBTAB(5)

NAME
     fbtab -- change device protection upon login

DESCRIPTION
     The fbtab file contains lines which specify how the permissions and own-
     ership of various system files should be changed based on the user's
     login device name.

     Comments start with a # and extend to the end of the line.  Blank lines
     or lines with only a comment are ignored.

     All other lines consist of three fields delimited by whitespace.

     Login Device          The device you have logged in on, ie. /dev/ttyv0.

     File Permission       An octal permission number (0600), as used by
                           chmod(2).

     Other devices         The final field is a ":"-delimited list of devices,
                           ie.  /dev/console:/dev/fd0a.  All device names are
                           absolute paths.  A path that ends in "/*" refers to
                           all directory entries except "." and "..".

     The fbtab file is used by login(1) to chown(2) the specified files to the
     user who has performed a login.  As well, chmod(2) is used to set the
     devices to the specified permission.  When a user logs out, init(8) is
     responsible for performing the inverse operation, this results in the
     files once again belonging to root.

FILES
     /etc/fbtab  The fbtab file resides in /etc.
