Chapter 9. Running External Programs

Sometimes, your code needs to interact with programs in the outside world, be it the operating system in which it runs, or other languages such as C or FORTRAN. This chapter shows how straightforward it is to run external programs from Julia and covers the following topics:

  • Running shell commands—interpolation and pipelining
  • Calling C and FORTRAN
  • Calling Python
  • Performance tips—a summary
