Julia is a high-level programming language that is used for numerical computing and data analysis. It is known for its speed and simplicity, making it a popular choice among scientists and researchers. One common question that arises when working with Julia is how to find the version number of the installed Julia software. In this article, we will explore three different ways to find the version number of Julia.
Option 1: Using the REPL
The Julia REPL (Read-Eval-Print Loop) is an interactive command-line interface that allows you to execute Julia code and get immediate results. To find the version number of Julia using the REPL, follow these steps:
julia> versioninfo()
Julia Version 1.6.2
Commit 1b93d53fc4 (2021-07-14 15:36 UTC)
Platform Info:
OS: Linux (x86_64-pc-linux-gnu)
CPU: Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz
WORD_SIZE: 64
LIBM: libopenlibm
LLVM: libLLVM-11.0.1 (ORCJIT, skylake)
By typing versioninfo() in the Julia REPL, you will get detailed information about the Julia version, commit, platform, CPU, word size, and LLVM. The Julia version is displayed as “Julia Version X.X.X”.
Option 2: Using the Pkg module
The Pkg module in Julia provides a set of tools for managing packages and dependencies. To find the version number of Julia using the Pkg module, follow these steps:
julia> using Pkg
julia> Pkg.status("Julia")
Status `~/.julia/environments/v1.6/Project.toml`
[c3e4b0f8] Julia v1.6.2
By using the Pkg.status("Julia") command, you can get the status of the Julia package. The version number is displayed as “Julia v1.6.2”.
Option 3: Using the command line
If you prefer using the command line, you can find the version number of Julia by executing the following command:
$ julia -v
julia version 1.6.2
By running the julia -v command in your terminal, you will get the Julia version number as “julia version 1.6.2”.
After exploring these three options, it is clear that the best option to find the version number of Julia depends on your preference and the context in which you are working. If you are already in the Julia REPL, using versioninfo() is the most convenient option. If you are managing packages or dependencies, using Pkg.status("Julia") is a good choice. And if you prefer the command line, using julia -v is the simplest option. Choose the method that suits your needs and workflow best.
