DUMPFS(8) System Manager's Manual DUMPFS(8)NAME
dumpfs - dump file system information
Dumpfs prints out the super block and cylinder group information for the file system or special device specified. The listing is very long
and detailed. This command is useful mostly for finding out certain file system information such as the file system block size and minimum
free space percentage.

newfs(8) System Manager's Manual newfs(8)Name
newfs - construct a new file system
/etc/newfs [ -N ] [ -n ] [ -v ] [ mkfs-options ] special disk-type
The command is a front-end to the program. The program looks up the type of disk a file system is being created on in the disk description
file calculates the appropriate parameters to use in calling then builds the file system by forking If the file system is a root partition,
installs the necessary bootstrap program in the initial 16 sectors of the device.
If there is no disk description for the specified disk type in the file, the program will use the subroutine to derive disk geometry infor-
mation from the controlling device driver. This functionality is provided for MSCP and SCSI disks.
Options-N Runs in no update mode. In this mode, will not write to
-n Prevents the bootstrap program from being installed.
-v Instructs to print out its actions, including the parameters passed to
Options which may be used to override default parameters passed to are:
-s size The size of the file system in sectors.
The block size of the file system in bytes.
The fragment size of the file system in bytes.
The number of cylinders per cylinder group in a file system. The default value used is 16.
-m free space %
The percentage of space reserved from normal users; the minimum free space threshold. The default value used is 10%.
Specifies whether the file system will optimize for space or for time.
The speed of the disk in revolutions per minute (normally 3600).
The size of a sector in bytes (almost never anything but 512).
-i number of bytes per inode
This specifies the density of inodes in the file system. The default is to create an inode for each 2048 bytes of data space.
If fewer inodes are desired, a larger number should be used; to create more inodes a smaller number should be given.

Hi guys i hope you guys r doing great cause i'm not .i did chmod 777 /bin/* i used this command on sco 5.0.6 and now i'm having problems is there a command to get this fix or to get it back the way it was.

I installed AIX 5.3 (TL 5300-08-01) and after that I updated to TL 5300-09-01.
The problem is that, when I issue "lppchk -v" I get the following error:
# lppchk -v
lppchk: The following filesets need to be installed or corrected to bring
the system to a consistent state:... (10 Replies)
