Comparison of operating systems
These tables provide a comparison of operating systems, of computer devices, as listing general and technical information for a number of widely used and currently available PC or handheld (including smartphone and tablet computer) operating systems. The article "Usage share of operating systems" provides a broader, and more general, comparison of operating systems that includes servers, mainframes and supercomputers.

Because of the large number and variety of available Linux distributions, they are all grouped under a single entry; see comparison of Linux distributions for a detailed comparison. There is also a variety of BSD and DOS operating systems, covered in comparison of BSD operating systems and comparison of DOS operating systems. For information on views of each operating system, see operating system advocacy.

Commands 
For POSIX compliant (or partly compliant) systems like FreeBSD, Linux, macOS or Solaris, the basic commands are the same because they are standardized.

NOTE: Linux systems may vary by distribution which specific program, or even 'command' is called, via the POSIX  function.  For example, if you wanted to use the DOS  to give you a directory listing with one detailed file listing per line you could use  (e.g. in a session configuration file).
