Is ios linux?
ios is not a linux system. iOS is actually an ARM variant of Darwin, derived from BSD, a UNIX-like kernel, and Apple's own Mach kernel extension system. Linux is also UNIX-like, but it is not BSD; Linux is a monolithic kernel, which means that all driver code and I/O toolkit are part of the core kernel. Essentially, macOS, iOS, BSD, and Linux are all siblings.

ios is not a linux system.
iOS is a mobile operating system developed by Apple. iOS, like Apple's macOS operating system, is a Unix-like commercial operating system.
iOS is actually an ARM variant of Darwin, derived from BSD, a UNIX-like kernel, and Apple's own Mach kernel extension system. This is completely different from Linux, which is a monolithic kernel, meaning that all driver code and I/O toolkit are part of the core kernel.
Apple is a hybrid kernel. Some live in the kernel, some are kernel extensions (usually .kext files). In comparison, Windows is a microkernel, meaning there is very little in the kernel and almost everything is an external driver.
Linux is also similar to UNIX, but it is not BSD. Linux actually came about because Linus Torvalds decided that he liked the concepts of UNIX and BSD, but he didn't like the execution of those projects. Essentially, macOS, iOS, BSD, and Linux are all siblings. Similar DNA, but different in their own rights, UNIX is the daddy.
"Linux OS" is actually GNU/Linux, which means that GNU provides the user with all the software tools (i.e. the commands you enter on the command line), while " Linux" is the kernel on which all tools reside. Linux was created by Linus Torvalds to avoid the licensing issues of using Minix or the cost issues of UNIX or Windows. He created it as a clone of Minix, which in turn was a UNIX replacement originally designed for academic use.
iOS is derived from macOS (OSX), which is derived from NextStep, which is derived from BSD Unix. So a cousin, but not Linux. Like Linux and MacOS, iOS is based on UNIX. The file structure and command set are the same, but the actual code is different and incompatible.
