körbar

Körbar is a Swedish term used in computing to describe software that can be executed directly by a computer. It refers to programs or code that the operating system can run without needing to be translated or compiled at the moment of execution. The term is commonly used for executable binaries as well as scripts that have the appropriate permissions or interpreter directives.

Two main forms are often described as körbara: native executables and interpreted scripts. Native executables consist of machine code produced by a compiler and are specific to a target architecture and operating system. Examples include ELF binaries on Linux, PE/COFF binaries on Windows, and Mach-O binaries on macOS. Interpreted scripts contain high-level language statements and are executed by an interpreter; they can be made executable on Unix-like systems by including a shebang line and granting execute rights. For example, a Python or Bash script may be run directly if it has a proper shebang and execute permission.

File permissions and associations govern how a file is treated as körbar. In Unix-like systems, the execute permission (the x bit) must be set for the user or others. In Windows, file extensions often signal executability, though some programs may rely on metadata or executable formats rather than extensions.

Portability and security are common considerations. Binaries are typically not portable across architectures or operating systems without recompilation, while scripts are more portable but require the appropriate runtime environment. Executing untrusted körbara files poses security risks, so integrity checks and trusted sources are important.
