version

What version do I have of ___?

You've been there...

java -v // unrecognized option
java -V // unrecognized option
java --version // unrecognized option
java --Version // unrecognized option
java -Version // unrecognized option
java -version // 1.8.0_262

There's no standard.

gcc --version
node -v
node --version
python -V
perl -v
perl --version
go version
lua -v
rustc --version

version is a simple, easily updateable script that tells you what version you are on. It has more than 200 apps registered with the syntax required to find version of that app. It will let you know what that syntax is, and then it'll run the command with that syntax and tell you what version you have (assuming the app is installed).

version node
# Command: node -v
# v18.13.0

version gcc
# Command: gcc --version
# gcc (Ubuntu 13.2.0-4ubuntu3) 13.2.0
# Copyright (C) 2023 ...

version vim
# Command: nvim -version
# NVIM v0.10.0-dev
# Build type: ...

version nix
# Command: nix --version
# But 'nix' 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.

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 (MacOS and Linux)
pip (MacOS and Linux)
flatpak (Linux)
brew (MacOS and Linux)
macports (MacOS)

Todo (potential):

Fink - MacOS
ZYpp - OpenSUSE
Portage - Gentoo
Nix - Nix

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:

Examples:

version libxml2
# version does not know about 'libxml2'
#   checking apt...
# libxml2 version: 2.9.14+dfsg-1.3

version systemd
# version does not know about 'systemd'
#   checking apt...
# systemd version: 253.5-1ubuntu6

version usbutils
# version does not know about 'setuptools'
#   checking apt...
#   checking snap...
#   checking npm...
#   checking pip...
# setuptools version: 68.2.2

version foo
# version does not know about 'foo'
#   checking apt...
#   checking snap...
#   checking npm...
#   checking pip...
# version was unable to find any info on 'foo'
