Hi to all of you,

In this post you will see how to split a file and for my example I use Ubuntu Linux 10.04 (32bit)

Let us assume that you need to send all the files in a folder to a friend. Select all the files and right-click on your selection -> choose Compress … and when the File Roller window appear give a name  to your archive.  Finally choose an extension – let say .tar.gz and hit Create button. All the files in your folder will be packed in a .tar file (container) and compressed with gzip.

And if, for instance, the final result is a 20 megabyte file you will maybe want to split it and send the pieces (chunks) in 2 or 3 electronic mails as attachments.

Here is how to find the decision of the task:

1. Install the tool that will be able to split the archive (on your computer). And that is the tool that your friend will use to merge the chunks on his machine (if he uses Ubuntu 10.04, let’s say).

In command line write down:

sudo apt-get install lxsplit

2. Do the job after installation.

cd /home/jack/Desktop/dox – and if in this directory is your packed archive, for example file.tar.gz

you can split it using lxsplit in command line:

lxsplit -s file.tar.gz 5m

-s means split the file

The result will be a few files with size not exceeding 5 megabytes each and extension .001, .002, …

Attach the files and send them to your recipient. He must download them and save all the files in one folder.

3. Join the files

Your friend will use the same program, already installed on his machine, to merge the files:

lxsplit -j file.tar.gz.001

-j means join the files

That’s all.

PS

Help for Windows users:

If your friend-recipient uses a Windows XP 32bit machine he will be able to merge the chunks using a program that does not need even an installation process.

Here is a link -

http://planetdes.files.wordpress.com/2011/03/hjsplit3-tar.xls

download the file and rename the .xls extension to .gz

>

Unpack this .tar.gz archive with a tool of your choice (WinRAR, IZArc, PowerArchiver, … ) and in the resulting folder you will find two files: hjsplit.exe and readme.txt.

I suggest you make a folder called HJSplit3 and move that folder to C:\Program Files.

Copy the files hjsplit.exe and readme.txt in C:\Program Files\HJSplit3 and place a shortcut on your Windows Desktop to the executable file hjsplit.exe

Run the executable, by activating the desktop shortcut, and you are ready to use the program HJ-Split:

Split a file of your choice or Join previously splitted files  -

in the first case just hit the Split button and locate the file you are going to split – use the appropriate button to finish you job.

in the second case – locate the folder in which you already placed all the files with .001, .002, … extensions. And choose, by HJ-Split, the first file  – with the extension .001  -  the rest is easy to finish the merging operation.

So in this article I want to say that Linux and Windows users can exchange archived/compressed files splitting them in order to transfer them via Internet.

A Windows user can create so called compressed/zipped folder by the operating system itself and in such a way avoiding to use commercial products (like for example WinRAR, …). A Linux user can create .zip archives too – FileRoller is a good front-end.

So thanks to HJ-Split the Windows user can split a big .zip archive and send it to a Linux user. The Linux user can merge the chunks using lxsplit in command line and finally get to the .zip archive, which can be easy extracted by FileRoller, for example.

The opposite – if a Linux user creates a .zip archive and splits it up into chunks he can send them to a Windows fellow through Internet. The Windows user can merge the chunks using HJ-Split.

And that is a real friendship between the two OS users. What do you think ?
