NAME
suffixes - list of file suffixes
DESCRIPTION
It is customary to indicate the contents of a file with the file suffix, which consists of a period, followed by one or more letters. Many standard utilities, such as compilers, use this to recognize the type of file they are dealing with. The make(1) utility is driven by rules based on file suffix. Following is a list of suffixes which are likely to be found on a Linux system. Suffix File type ,v files for RCS (Revision Control System) - backup file .C C++ source code, equivalent to .cc .F Fortran source with cpp(1) directives or file compressed using freeze .S assembler source with cpp(1) directives .Y file compressed using yabba .Z file compressed using compress(1) .[0-9]+gf TeX generic font files .[0-9]+pk TeX packed font files .[1-9] manual page for the corresponding section .[1-9][a-z] manual page for section plus subsection .a static object code library .ad X application default resource file .ada Ada source (may be body, spec, or combination) .adb Ada body source .ads Ada spec source .afm PostScript font metrics .al Perl autoload file .am automake(1) input file .arc arc(1) archive .arj arj(1) archive .asc PGP ASCII-armored data .asm (GNU) assembler source file .au Audio sound file .aux LaTeX auxiliary file .avi (msvideo) movie .awk AWK language program .b LILO boot loader image .bak backup file .bash bash(1) shell script .bb basic block list data produced by gcc -ftest-coverage .bbg basic block graph data produced by gcc -ftest-coverage .bbl BibTeX output .bdf X font file .bib TeX bibliographic database, BibTeX input .bm bitmap source .bmp bitmap .bz2 file compressed using bzip2(1) .c C source .cat message catalog files .cc C++ source .cf configuration file .cfg configuration file .cgi WWW content generating script or program .cls LaTeX Class definition .class Java compiled byte-code .conf configuration file .config configuration file .cpp equivalent to .cc .csh csh(1) shell script .cxx equivalent to .cc .dat data file .deb Debian software package .def Modula-2 source for definition modules .def other definition files .desc initial part of mail message unpacked with munpack(1) .diff file differences (diff(1) command output) .dir dbm data base directory file .doc documentation file .dsc Debian Source Control (source package) .dtx LaTeX package source file .dvi TeX's device independent output .el Emacs-Lisp source .elc compiled Emacs-Lisp source .eps encapsulated PostScript .exp Expect source code .f Fortran source .f77 Fortran 77 source .f90 Fortran 90 source .fas precompiled Common-Lisp .fi Fortran include files .fig FIG image file (used by xfig(1)) .fmt TeX format file .gif Compuserve Graphics Image File format .gmo GNU format message catalog .gsf Ghostscript fonts .gz file compressed using gzip(1) .h C or C++ header files .help help file .hf equivalent to .help .hlp equivalent to .help .htm poor man's .html .html HTML document used with the World Wide Web .hqx 7-bit encoded Macintosh file .i C source after preprocessing .icon bitmap source .idx reference or datum-index file for hypertext or database system .image bitmap source .in configuration template, especially for GNU Autoconf .info files for the Emacs info browser .info-[0-9]+ split info files .ins LaTeX package install file for docstrip .itcl itcl source code;

Opportunity
Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.
Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.
Free Software
Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.
Free Books
The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.
Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.
Education
Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.
