How do I create chunks (blocks) not raw devices in linux ?

I have 800GB and i need to create 80 chunks of 8GB and 10 chunks of 16GB.
80x8GB + 10x16GB = 800GB

Can someone tell me what commands do i need to use in order to create those chunks ?

What is the context of this question----eg What problem are you trying to solve?

I assume you have an 800GB hard drive. Do you want to fill it with data? (data from what source?) ....partitions?

I can't explain better than that.

For example when i do ls -all i need to see c not r (blocks mean C).

Ummmmm---can you at least answer my specific questions???
You want to see "c" and not "r"? where??

When I do ls -all, all I can see is the contents of the directory with respective permissions on files and sub-directories.

Eg:
-rwxrwxrwx 1 inspire inspire 0 2009-01-23 18:25 test

Now r there means its readable.

noobs...

Excuse me???

When you are asked for clarification of your question, I am not sure how to interpret a response like this.

fdisk or gparted have any options for this?

# cd xxxxx
# ls -all
total 16

See? C ! It's C ! It's C not R !

What do you mean by chunks? What are you trying to do? You listed a bunch of character devices and talk about C and R.
You also concealed what directory you are listing. Are you trying to repartition a drive or break up a very large file into slices?

I need to create 80 chunks of 8GB and 10 chunks of 16GB. After that, when i enter in a chunk, i need to see the first letter C not r when i do ls -all.

You still haven't explained what a chunk is. Also, a long listing including hidden files is "ls -a".

What do you mean my first letter? Are you referring to the the "c" filetype indicator? There is no "R" filetype.
How did you create the character devices you listed?

I hope you have understood what "c" there means from the previous post from jschiwal. Now if you could answer his post it would give you your solution that you need.

I don't know how and what should i explain.
I need to create those partitions in character mode. (C stands for character) not binar or whatever.

ytd;

Please read the entire thread and answer the questions which people have now asked you several times.
If there is a language barrier here, then you might want to get someone to help you.....

For example:

What is a "chunk"?

Are you trying to create partitions, files, devices, or ???

Most important: What is the context of the question? In other words, what is the overall goal?


The "c" prefix on a file is typically seen only in the /dev directory, and means that the device is a character device---for example, a keyboard. The prefixes listed by jschiwal are not used with partitions. (You cannot "create a partition in character mode")
