shellcompatible
Shellcompatible is a designation used in software development to indicate that a program, script, or library can be executed reliably across a broad range of shell environments without relying on shell-specific extensions. It signals adherence to portable shell practices and predictable behavior in both interactive and automated contexts.
It targets interoperability across common Unix-like shells such as POSIX sh, Bash, Dash, Zsh, and BusyBox sh,
Conformance criteria typically include: implementation in a POSIX-compliant manner; avoidance of non-portable extensions; minimal reliance on
Adopting shellcompatibility improves portability of CLI tools, installation scripts, and automation workflows, reduces platform-specific maintenance, and
