ncheck(8)							     ncheck(8)

       ncheck  -  Lists i-number or tag and pathname for files in a local file

       /usr/sbin/ncheck	  [-i	numbers]   [-asm]    [device_special_file    |

       Includes in the list the pathnames (dot) and (dot dot), which are ordi‐
       narily suppressed.  Lists only those existing files with the  specified
       i-numbers  (UFS)	 or tags (AdvFS).  Includes in the list the mode, UID,
       and GID of the files.  To use this option you must also specify	either
       the  -i or the -s option from the command line.	Lists only the special
       files and files with set-user-ID mode.

       Specifies one or more file systems.  Specify a file system by  entering
       its device special file name or AdvFS domain as shown in the /etc/fstab
       file as follows: Specify a UFS file system by entering the name of  its
       device  special file.  For example: /dev/disk/dsk3c. You can also spec‐
       ify the raw device, such as /dev/rdisk/dsk4a.  You cannot  specify  the
       UFS  mount  point,  such as /usr or the following message is displayed:
       ncheck: cannot open /usr: Device	 busy  Specify	an  AdvFS  fileset  by
       entering	 the  name of the file domain, a pound sign (#) character, and
       the name of the fileset.	 For example: root_domain#root.

       The ncheck command with no options generates a list  of	all  files  on
       every  specified	 file system.  The list includes the path name and the
       corresponding i-number or tag of each file. Each directory file name in
       the list is followed by a /.  (slash dot). Use the available options to
       customize the list to include or exclude specific types of files.

       The files are listed in order by i-number or tag. To sort the list in a
       more useful format, pipe the output to the sort command.

       To  uncover concealed violations of security policy, that is, the inap‐
       propriate use of the set-user-ID mode, issue the command	 with  the  -s
       option to list only special files and files with set-user-ID mode.

       You must be the root user to use this command.

       The  ncheck command checks the /etc/fstab file for the specified domain
       and file system entry. If there is no entry in /etc/fstab for the spec‐
       ified  file system, an error message is displayed to  indicate that the
       file does not exist.

       The ncheck command can be used only for checking	 local	file  systems.
       The  "nnn"  string  identifies the file system type.  Specify the AdvFS
       domain instead of the file system path (such as /var).

       When the file system structure is improper, ??  (question mark question
       mark)  denotes  the parent of a parentless file.	 A path name beginning
       with (dot dot dot) denotes a loop.

       The following example shows command options taking data from  a	sample
       /etc/fstab  file:  # more /etc/fstab /dev/disk/dsk4a /	    ufs rw 1 1
       /proc	       /proc   procfs rw 0 0 usr_domain#usr  /usr    advfs  rw
       0 2 var_domain#var  /var	   advfs rw 0 2 # /usr/sbin/ncheck /usr cannot
       ncheck "advfs" filesystem # /usr/sbin/ncheck usr_domain#usr

       usr_domain#usr:	  3	     /.tags/.	  4	     /quota.user     5
       /    .     .	   .	#   /usr/sbin/ncheck   /dev/disk/dsk4a
       /dev/rdisk/dsk4a (/dev/disk/dsk4a): 3200	   /cluster/.  12801	/etc/.
       .  .  .	# /usr/sbin/ncheck / ncheck: cannot open /: Device busy

       Specifies the command path.
