       fsck.minix - a file system consistency checker for Linux

SSYYNNOOPPSSIISS

DDEESSCCRRIIPPTTIIOONN
       ffsscckk..mmiinniixx  performs  a	consistency  check  for the Linux
       MINIX filesystem.  The current  version	supports  the  14
       character and 30 character filename options.

       The   program   assumes	the  file  system  is  quiescent.
       ffsscckk..mmiinniixx should not be used on a mounted  device  unless
       you can be sure nobody is writing to it (and remember that
       the kernel can write to it when it searches for files).

       The device will usually have the following form:
	      /dev/hda[1-8]
	      /dev/hdb[1-8]
	      /dev/sda[1-8]
	      /dev/sdb[1-8]

       If the file system  was	changed	(i.e.,	repaired),  then
       ffsscckk..mmiinniixx  will	print "FILE SYSTEM HAS CHANGED" and will
       ssyynncc(2) three times before exiting.  Since Linux does  not
       currently  have raw devices, there is _n_o need to reboot at
       this time (versus a system which _d_o_e_s have raw devices).

WWAARRNNIINNGG
       ffsscckk..mmiinniixx should nnoott be used  on  a  mounted  filesystem.
       Using  ffsscckk..mmiinniixx  on a mounted filesystem is very danger-
       ous, due to the possibility that deleted files  are  still
       in use, and can seriously damage a perfectly good filesys-
       tem!  If you  absolutely	have  to  run	ffsscckk..mmiinniixx  on	a
       mounted	filesystem (i.e., the root filesystem), make sure
       nothing is writing to the disk,	and  that  no  files  are
       "zombies" waiting for deletion.

OOPPTTIIOONNSS
       --ll     Lists all filenames

       --rr     Performs interactive repairs

       --aa     Performs	automatic  repairs  (this  option implies
	      --rr), and serves to  answer  all  of  the	questions
	      asked  with  the	default.   Note	that this can be
	      extremely dangerous in the case of  extensive  file
	      system damage.

       --vv     Verbose

       --ss     Outputs super-block information

       --mm     Activates MINIX-like "mode not cleared" warnings

       There  are  numerous  diagnostic	messages.  The ones men-
       tioned here are the most commonly seen in normal usage.

       If the  device  does  not  exist,  ffsscckk..mmiinniixx  will  print
       "unable	to  read super block".	If the device exists, but
       is not a MINIX file system,  ffsscckk..mmiinniixx	will  print  "bad
       magic number in super-block".
