mtab(4)                                                   mtab(4)



NAME
     mtab - mounted file system table

DESCRIPTION
     mtab contains a record of all file systems, directories, and
     files mounted on the computer.  Whenever mount mounts a file
     system, directory, or file, it makes an entry  in  the  mtab
     file.  Whenever umount unmounts a file system, directory, or
     file, it removes the corresponding entry.

     The table is a series of lines with form identical  to  that
     of  /etc/fstab.   The lines contain keywords and values that
     are documented in mount(1M) and fstab(4).   Each  line  also
     contains  the  keyword  dev whose value identifies the major
     and minor device number in hexadecimal of the  mounted  file
     system. For NFS mounts, the major number is 81 and the minor
     number is 01 for the first NFS mount, 02 for the second  NFS
     mount, and so on.

     Each NFS entry mounted by automount  begins  with  the  host
     name of the computer and the process ID of automount and may
     contain one or more of the following keywords:

     direct
          Specifies that the map specified by  map  is  a  direct
          map.

     indirect
          Specifies that the map specified by map is an  indirect
          map.

     map  Specifies the name of the map used to make this mount.

     port Specifies the port being used.

FILES
     /etc/mtab
          File maintained by mount to record the current mounts
