  Behavior flags

    •  dry_run = false skip the actual download and installation

    •  verbose = dry_run print the final value of all arguments

    •  migrate_packages = <upgrading to a later version of Julia without an existing
       global environment> whether to migrate packages in the default global environment.
       May be true, false, or :force. Only :force will replace an existing Project.toml

  Destination

    •  aliases = ["julia", "julia-$(v.major).$(v.minor)", "julia-$v"] which aliases to
       attempt to create for the installed version of Julia. Regardless, will not
       replace stable versions with less stable versions or newer versions with older
       versions of the same stability.

    •  systemwide = ... install for all users, false only installs for current user.

    •  install_location = systemwide ? "..." : "..." directory
       to put installed binaries

    •  bin = systemwide ? "..." : "..." directory to store links
       to the binaries

  Source

    •  os_str = "..." string representation of the operating system: "linux", "mac",
       "winnt", or "freebsd".

    •  arch = "..." string representation of the CPU architecture: "x86_64", "i686",
       "aarch64", "armv7l", or "powerpc64le".

    •  v = ... the VersionNumber to install

    •  url = ... URL to download that version from, if you explicitly set url, also
       explicitly set v lest they differ

The system dependent portions are replaced with ....

Install locations

UpdateJulia will download Julia from https://julialang-s3.julialang.org/bin/<os>/<arch>/<version>/julia-<version>-<os>.<extension>, unpack the contents of the download to an install location, and then link the executable in the install location to a symlink in a bin that should be on PATH. The exact install and bin locations depend both on operating system and on whether you choose to install Julia for the current user only systemwide = false or for every user on the system systemwide = true.

OS	System install	System bin	User install	User bin
Unix	/opt*	/usr/local/bin	~/.local*	~/.local/bin
Mac	/Applications	/usr/local/bin	~/Applications	~/.local/bin
Windows	\Program Files	automatically add install location to path	~\AppData\Local\Programs	automatically add install location to path

* Unix has somewhat loose conventions for install locations. If you already have Julia installed in a location that falls within those conventions, UpdateJulia will install the new version of Julia right next to the one you are currently using.
