90% of the world's most powerful supercomputers using an operating system GNU / Linux, in fact, the top ten of supercomputers use Linux. In fact, the penetration of Linux in data centers is very high, 33.8% of the world runs on Linux servers compared to 7.3% does so in a Microsoft operating system. For example, Google's servers run on Linux, like the server hosting the website of the White House.
Linux Earlier Years
The first commercial distribution GNU / Linux was Yggdrasil was launched Lice-CD format in 1992. Red Hat was one of the first distributions to settle within companies and data centers in 1999. Debian was one of the first GNU / Linux that was constituted and organized as a community of developers.
Linux OS used in Major Applications / Services
Linux is present in highly critical applications such as Japan's bullet trains, traffic control, San Francisco, the New York Stock Exchange, CERN, many air traffic control systems or control of nuclear reactors of submarines and ships many nuclear war.
Expanding Everyday
Linux has more than 9.2 million lines of code and this amount grows 10% each year. Of the 9.2 million lines, the kernel itself accounts for 5% and 55% drivers. Add lines 4500, 1800 and 1500 are removed are changed every day.
Widely Used
Linux is now one of the most widely ported operating system kernels, running on a diverse range of systems from handheld computers to mainframe servers.

rsync is a software application and network protocol for Unix-like and Windows systems which synchronizes files and directories from one location to another while minimizing data transfer using delta encoding when appropriate. An important feature of rsync not found in most similar programs/protocols is that the mirroring takes place with only one transmission in each direction. rsync can copy or display directory contents and copy files, optionally using compression and recursion.
Trouble with rsync while transfering to a server with port number ??
Here is the correct syntax :
There are 2 ways to use this command.
1. If you are trying to transfer the files from remote server to your system then use the syntax below:
-----
rsync -avz -e "ssh -p $portNumber" user@remoteip:/path/to/files/ /local/path/
-----
2. If you are trying to transfer the files from your system to remote server then use the syntax below:
-----
rsync -avz /local/path/ -e "ssh -p $portNumber" user@remoteip:/path/to/files/
