how to split a file in linux

If you need to split a single large file into smaller pieces to transfer the files through small memory drives(I had to transfer 4.6 GB matlab ISO using two 4 GB pendrives), there's this simple command line tool called "split" developed by Torbjorn Granlund and Richard M. Stallman.


Fire up the terminal and navigate to the directory in which the file to be splitted is present.

Then, we'll use the split command as below:

split --bytes=2G matlab.iso matlab_

After executing the above command, the iso is divided into smaller chunks of specified file size. The --bytes option can take various different arguments such as 2K, 2M, etc.

To recombine the files into a single file, open the terminal and type the following after navigating to the proper directory.

cat matlab_* > matlab.iso

For more information on the command, type man split.

Online Alternative To Matlab

Today, I visited a website which provided the service of working on Matlab online in a website without any need of installing Matlab software. Although not comprehensive as the software itself, this web version can be quite useful in some cases.

This site offers as of now more than 500 Matlab R2009A commands. Only text commands are supported for now and they are working for graphical supports such as plots.

Thanks to Brisha for pointing this useful site. :)

Advanced HTTP Fingerprinting With httprecon

One of the first steps in web server hacking involves fingerprinting to gather information regarding the web server and various mods applied to it. Fingerprinting the web server manually can be cumbersome so some good folks have developed an advanced open-source fingerprinting tool known as httprecon

*Description from official webpage:

The httprecon project is doing some research in the field of web server fingerprinting, also known as http fingerprinting. The goal is the highly accurate identification of given httpd implementations. This is very important within professional vulnerability analysis.

Besides the discussion of different approaches and the documentation of gathered results also an implementation for automated analysis is provided. This software shall improve the easyness and efficiency of this kind of enumeration. Traditional approaches as like banner-grabbing, status code enumeration and header ordering analysis are used. However, many other analysis techniques were introduced to increase the possibilities of accurate web server fingerprinting.

MidpSSH: SSH and Telnet Client For J2ME Phones

MidpSSH is an SSH and Telnet client for MIDP 1.0 / 2.0 (J2ME) devices such as Java™-capable cellphones and other mobile devices.

MidpSSH provides SSH (Secure Shell) and Telnet functionality on mobile devices such as cellphones. This is really useful for people who need to access a server wherever they are, without carrying around a computer or searching for an Internet connection. Because the screen is small, the connection is often slow, and you’re possibly without a full keyboard, it isn’t great for prolonged use - but if you’re desperate it’s a life saver.

For downloading and more information, go to the official site.

I hope this tool comes useful for you sometimes. :)
