You can learn to program in Linux® by becoming familiar with the operating system interface, learning how to use the command line correctly, and mastering at least one programming language commonly used with the Linux® platform. Many entry-level Linux® programmer jobs require certification in the vendor-neutral Linux®+ exam objectives. Because a large amount of material is freely available for you to learn and practice at your own pace, becoming a Linux® programmer can often be done on your own. If you have a prior background in computer programming or system administration, this option is usually the most effective. If you feel you need more help, many two-year colleges and technical schools offer programs that will prepare you for a career as a Linux® programmer.
Understanding open-source software and its associated requirements is one of the first steps toward becoming a Linux® programmer. Linux® programmers create source code and make it available for other programmers to examine and edit as they see fit. Examining some of these code samples will provide you with a good understanding of the structure and syntax of a good Linux® software application. You can usually find plenty of free tutorials and even full-length textbooks to get you started on the basics of navigating the Linux® command line in addition to source code samples.
Programming in the Linux® operating system also necessitates familiarity with using a terminal rather than a graphical user interface to navigate and modify the system. This method gives a Linux® programmer more control over system adaptations as well as the creation of new programs from scratch. Rather than using a compiling program called an integrated development environment, some Linux® programmers code in a terminal mode editor (IDE). You’ll have more flexibility learning the languages required to become a Linux® programmer if you can program in both an IDE and the Linux® terminal mode.
To become a Linux® programmer, you’ll need to know at least one programming language. Beginning programming courses in languages like C, Java®, C++, and Perl are available at many adult vocational schools and two-year colleges. If you have no prior computer programming experience, these courses can provide a solid foundation. The same school programs may also offer courses to prepare you for the Linux®+ certification, which is useful for a variety of entry-level Linux® programmer jobs. Completing a two-year computer science degree with a focus on Linux® programming will also qualify you for a variety of jobs.
