Perl for different operating systems

  • UNIX / Linux: users of these operating systems typically need not worry about installing Perl as UNIX-like operating systems come with Perl pre-installed; users might just want to check the version of Perl installed on their system if they have special requirements concerning the version
  • Mac OS: as Mac OS is a UNIX-like operating system Perl is pre-installed, see above
  • Windows: Windows does not ship with Perl pre-installed, but Perl is freely available and the installation simply requires downloading a single file and executing it. Alternatively, Strawberry Perl is a freely available distribution that is widely recommended for Windows in the community. Just download the current installation file for your operating system, run the executable file and you are set.
