Unix-like

*A Unix-like operating system, often referred to as UN*X or nix, behaves similarly to a Unix system; however, there is no official technical standard defining this term, leading to varying opinions on how closely an operating system resembles Unix. While IBM i does not directly run Unix or Linux, it offers some Unix-like capabilities through key technologies :

• PASE (Portable Application Solutions Environment) is a runtime environment that allows AIX applications to run on IBM i.
• Qshell is a Unix-like command line interface and scripting environment for IBM i. It provides a shell, commands and scripts.
• Open source technologies commonly found on Unix/Linux systems, including languages like Python, Node.js, PHP, web servers like Apache and databases like MySQL.
• While IBM i cannot natively run Linux containers, it can integrate with Linux environments running containers, like MERLIN (Modernization Engine for Lifecycle Integration) which is an IBM i development tool.

UNIX was called UNICS (Uniplexed Information and Computing Service)

PASE (Portable Application Solutions Environment)

PASE is an environment, a set of shared libraries that enable some Unix (AIX) functions like binaries to run natively which allows the execution of AIX applications directly on the IBM i. SSH (Secure Shell) login with keys will allow you to authenticate to your IBM i partition and connect more securely.

/QOpenSys/usr/bin: contains standard Unix-like utilities and commands that are part of the base operating system

/QOpenSys/pkgs/bin: used for additional software packages (third-party applications) that are installed on the system
