Ever have to check a list of Linux servers for various things like what version of CentOS they’re running, maybe how long each has been running to get an uptime report? You can and it’s very easy to get going with it with the command gsh

Group Shell (also called gsh) is a remote shell multiplexor. It lets you control many remote shells at once in a single shell. Unlike other commands dispatchers, it is interactive, so shells spawned on the remote hosts are persistent.
It requires only a SSH server on the remote hosts, or some other way to open a remote shell.

Linux
GNU/Linux is one of the most rapidly growing open source operating system as it is consistently improving its capabilities to meet the technological requirements. Initially, Linux was not adopted by most of the users because of its command line interface but later developments in Linux provide ease in terms of accessibility and offered Graphical User-Interface (GUI). As it’s an open source OS, it has one of the largest developer community and one of the most prominent contributors in Linux technology is RedHat. Linux was initially designed for Intel x86 personal computers and then later on modified to support different hardware as well.

If you consider that many things such as recipes, formulas and even patents have been shared since the beginning of time, you’ll realize that this was by no means a new idea.

In 1991, the Linux Kernel, which was started by Linus Torvalds, was released as a freely modifiable source code. Initially the license wasn’t the GPL, but in February 1992 when version 0.12 was released, Torvalds made sure he licensed it under the GNU General Public License. Torvalds was delighted that his kernel attracted much attention from volunteer programmers.

Up until this point no completely free-software operating systems were in existence due to the GNU’s lack of a working kernel, but the development of Torvalds’s kernel proved to be the final piece of the puzzle.
