hello all,
i want to know the major differences between the unix filesystem and the linux ext filesystem i.e the datastructure or additional attributes that makes up the major difference.
i would also like to know what operating systems currently use ufs1 and ufs2.
help me
thanx in advance
In the awk I am trying to subtract the difference $3-$2 of each matching $4 before the first _ (underscore) and print that value in $13.
I think the awk will do that, but added comments. What I am not sure off is how to add a line or lines that will add sum each matching $13 value and put it in... (2 Replies)
I think both write at the end of the file ......
but is there a sharp difference between those 2 instruction .....
thank you
this is my 3rd question today forgive me :D (1 Reply)
Hi All,

I dont know whether it will give any impact... (2 Replies)
Hi All,
I need to expand a number of Filesystems on a Sun machine running Solaris 10 OS. But first I am confused;
1. Is it possible to expand a ufs filesystem such as /dev/dsk/c1t1d0s0 (that is not managed by SVM) without lossing existing data?
2. Is it possible to have such a... (7 Replies)
I have a couple of servers where something weird is going on. When I run the command "mount | grep logging" I get something similair to this

But when I look at /etc/vfstab I dont... (6 Replies)

Hi all, I have FreeBSD and Debian in my HD, the FreeBSD partition is very small and I'd like to change. I try to use partition magic but it does not work with UFS parition. Anyone know a good partition software? (1 Reply)

mkfs - build a Linux filesystem
SYNOPSIS SYNOPSIS
mkfs [options] [-t type fs-options] device [size]
DESCRIPTION
mkfs is used to build a Linux filesystem on a device, usually a hard disk partition. The device argument is either the device name (e.g.
/dev/hda1, /dev/sdb2), or a regular file that shall contain the filesystem. The size argument is the number of blocks to be used for the
filesystem.
The exit code returned by mkfs is 0 on success and 1 on failure.
In actuality, mkfs is simply a front-end for the various filesystem builders (mkfs.fstype) available under Linux. The filesystem-specific
builder is searched for in a number of directories, like perhaps /sbin, /sbin/fs, /sbin/fs.d, /etc/fs, /etc (the precise list is defined at
compile time but at least contains /sbin and /sbin/fs), and finally in the directories listed in the PATH environment variable. Please see
the filesystem-specific builder manual pages for further details.
OPTIONS -t, --type type
Specify the type of filesystem to be built. If not specified, the default filesystem type (currently ext2) is used.
fs-options
Filesystem-specific options to be passed to the real filesystem builder. Although not guaranteed, the following options are sup-
ported by most filesystem builders.
-V, --verbose
Produce verbose output, including all filesystem-specific commands that are executed. Specifying this option more than once
inhibits execution of any filesystem-specific commands. This is really only useful for testing.
-V, --version
Display version information and exit. (Option -V will display version information only when it is the only parameter, otherwise it
will work as --verbose.)
-h, --help
Display help and exit.
BUGS
All generic options must precede and not be combined with filesystem-specific options. Some filesystem-specific programs do not support
the -V (verbose) option, nor return meaningful exit codes. Also, some filesystem-specific programs do not automatically detect the device
size and require the size parameter to be specified.
