Solaris

Hi!

I've been wondering what is the file extension for an image file in Solaris. For Windows, I know it's .jpeg or .bmp or .png and etc. What do Solaris call their image file extensions then?

I just know how to make a file by the use of this command:

Code:

  # mkfile 1000k /dev/rdsk/c7t0d0s0

But, I need an image file in the disk. That code does not seem to make an image file.

And if possible, how can I make an image file located at the disk, for example, at disk c7t0d0s0 because I will later use it for mirroring.

Thanks!

Image is a term with several meanings.

First off, an extension, all by itself does not proclaim a file type in UNIX. The file command will tell you what kind of file you have, based on a "magic number" (really a header). Windows does not do that.

A graphics file is one of a lot of formats - jpeg, mpeg, png, etc. So it has a header particualr to the format.

An image is a copy of an executable, usually image files in the sense I think you mean are copies of the kernel. The name comes from the fact that the executable file many years ago was an image (almost exact duplicate) of what the executable looked like in memory. This is not necessarily true now, except in some cases.

More to the point - what are you trying to do? graphics?

I am trying to save a graphics file (as you say so), on the disk.

Does Solaris support a .jpeg file?

I have already figured it out.

I made a screenshot and placed it on the desktop. It is named Screenshot.png

Now, my question is that, if it is placed on the desktop, does it also mean that the file is in the disk also? for example, disk c0t0d0s0. Does that mean that Screenshot.png is contained in the c0t0d0s0 disk?

Thanks!

Solaris support files, all of them and whatever their contents and extensions. It is stored on a file system. This file system is more than likely backed by your internal disk on your machine. On large Solaris deployments, It might be elsewhere on remote shared file systems.

Ahhh...

If I need to mirror my Screenshot.png file located at rpool, what will I do?

I just know how to mirror a boot disk, but how to mirror a file using the terminal, i really don't know.

May I also ask what are these icons for? (See the image below)

I found there my disk c7t0d0s0 and c7t2d0s0, but why are they so many?
When I'm using # format in the terminal, only those 2 disks are present?

You don't mirror files, you mirror devices. Anything using these devices like file systems and files inside them are automatically duplicated.

These icons are showing both existing and potential partitions and slices. You shouldn't worry or even care about them.
