version is a simple, easily updateable script that tells you what version you are on.
version node // v14.70
version gcc // 10.1.0
version java // 1.8.0_262
version pascal // 'pascal' does not seem to be installed.
But wait, there's more!
version also uses the package manager on your system to find the versions of programs and libraries that it doesn't know about itself. This puts the number of items that version can report the version of into the thousands. This includes libraries which are not directly executable, so don't have a version flag. Examples:
version libxml2 // 2.9.10-2
version usbutils // 012-2
version systemd // 246.4-1
This feature currently supports the package managers:
apt(Linux - Debian, Ubuntu, and derivatives)pacman(Linux - Arch, Manjaro, and deriviatives)dnf(Linux - Fedora and derivatives)snap(Linux)npm(Mac and Linux)pip(Mac and Linux)flatpak(Linux)brew(Mac and Linux)
If version doesn't know about the command, it will start searching through any of the package managers that are installed and report what it finds:
