In addition, "Hello, world!" can be a useful sanity test to make sure that a language's compiler, development environment, and run-time environment are correctly installed. Configuring a complete programming toolchain from scratch to the point where even trivial programs can be compiled and run can involve substantial amounts of work. For this reason, a simple program is used first when testing a new tool chain.
==ಇತಿಹಾಸ==
==History==
While small test programs existed since the development of programmable [[ಗಣಕಯಂತ್ರ|computer]]s, the tradition of using the phrase "Hello, world!" as a test message was influenced by an example program in the seminal book ''The C Programming Language''<sup class="noprint Inline-Template Template-Fact" style="white-space: nowrap;" contenteditable="false">&#x5B;<i>citation needed</i>&#x5D;</sup>. The example program from that book prints "<code>hello,&nbsp;world</code>" (without capital letters or exclamation mark), and was inherited<sup class="noprint Inline-Template Template-Fact" style="white-space: nowrap;" contenteditable="false">&#x5B;<i>citation needed</i>&#x5D;</sup> from a 1974 Bell Laboratories internal memorandum by Brian Kernighan, ''Programming in C: A Tutorial'',<ref name="ctutorial">{{cite web| url = http://cm.bell-labs.com/cm/cs/who/dmr/ctut.pdf| title = Programming in C: A Tutorial}}</ref> which contains the first known version:
==Variations==
 
The Debian and [[ಉಬುಂಟು|Ubuntu]] [[ಲಿನಕ್ಸ್|Linux]] distributions provide the "hello world" program through the apt packaging system; this allows users to simply type "apt-get install hello" for the program to be installed, along with any software dependencies. While of itself useless, it serves as a sanity check and a simple example to newcomers of how to install a package. It is significantly more useful for developers, however, as it provides an example of how to create a .deb package, either traditionally or using debhelper, and the version of hello used, GNU Hello, serves as an example of how to write a GNU program.
