NAME
     mountall, umountall - mount, unmount multiple file systems

SYNOPSIS
     mountall  [ -F FSType ]  [-l  | -r ]  [ file_system_table ]

     umountall  [ -k ]  [ -s ]  [ -F FSType ]  [-l  | -r ]

     umountall  [ -k ]  [ -s ]  [ -h host ]

DESCRIPTION
     mountall  is used to mount file systems specified in a  file
     system  table.   The  file system table must be in vfstab(4)
     format. If no  file_system_table is  specified,  /etc/vfstab
     will  be  used.   If  `-' is specified as file_system_table,
     mountall  will read the file system table from the  standard
     input.   mountall   only  mounts those file systems with the
     mount at boot field set to yes in the file_system_table.

     Each file system which has an  fsckdev  entry  specified  in
     the  file  system  table  will  be checked using fsck(1M) in
     order to determine if it may be safely mounted. If the  file
     system  does  not  appear mountable, it is fixed using  fsck
     before the mount is attempted.   File  systems  with  a  `-'
     entry  in  the   fsckdev field will be mounted without first
     being checked.

     umountall  causes all  mounted  file  systems  except  root,
     /proc,   /var,  and  /usr  to be unmounted. If the FSType is
     specified, mountall  and umountall  limit their  actions  to
     the  FSType specified. There is no guarantee that  umountall
     will unmount busy filesystems, even if  the   -k  option  is
     specified.

OPTIONS
     -F        Specify the  FSType  of  the  file  system  to  be
               mounted or unmounted.

     -h host   Unmount all file systems  listed  in   /etc/mnttab
               that are remote-mounted from host.

     -k        Use the  fuser -k  mount-point  command.  See  the
               fuser(1M)  for  details.  The  -k option sends the
               SIGKILL signal to each process using the file.  As
               this  option  spawns  kills  for each process, the
               kill messages may not show up  immediately.  There
               is no guarantee that  umountall  will unmount busy
               filesystems, even if the  -k option is specified.

     -l        Limit the action to local file systems.

     -r        Limit the action to remote file system types.
