Create 10000 files, (filename can be just combination of time and random number).
File size should be 4k.
And I want to time this. say how many seconds it will take.
How can I do this on bash?
Thank you.
time for x in {1..10000}; do
dd if=/dev/zero ibs=4k count=1 of=$x.txt 2>/dev/null

So I have an encrypted text I need to decrypt, where do I start and is there a program that automatically recognizes an algorithm ? Here is a snippet of what I need decrypted:

Encrypted text is designed to resemble random numbers. Cryptographic algorithms are designed specifically to keep you from doing exactly what you are trying to do.

I am wanting to learn the ropes with 7z. This isn't working...I followed 7z --help:
7z x -r beans.7z personal.php
I want to make a .7z file called "beans.7z" and what contains the file "personal.php"
The error I get is:
Error:
there is no such archive
Here is the correct command for what you want to do:
7z a beans.7z personal.php

I don't know why I have this strange error when using Octave on Windows 7 64 bit :
when I use ones(100:100) to declare a matrix 100x100. No problem. But when I use : ones(10:100) I will have error :
memory exhausted or requested size too large
And if I use ones(10:15) I must wait for long time (about 30 seconds) to have answer.
Please explain for me this error.
Thanks :)
Your syntax is wrong. To create an m x n matrix it should be:
ones(m,n)
e.g.
ones(100,100)
or
ones(10,15)

How do I display the current time? Please give me an example.
I know about msdn but still have a problem.
Please use by trying DateTime.Now to access the current time.
