ARDUINO-CLI-CORE-UPGRADE(1)

💖 arduino-cli-core-upgrade — the glow-up page 💖

okay so bestie, welcome to the ARDUINO COMMAND LINE MANUAL, section 1. this is the manual page for arduino-cli-core-upgrade, and yes it's giving "make my platforms pretty" energy, because that's literally what it does. sit down, grab a boba 🧋, and let's get into it.

---

✨ NAME ✨

arduino-cli-core-upgrade — upgrades one or all installed platforms to the latest version. lowkey the whole point of existing. 💅

---

✨ SYNOPSIS ✨

arduino-cli core upgrade [PACKAGER:ARCH] ... [flags]

so you can name zero, one, or honestly a whole lil lineup of PACKAGER:ARCH things, and then sprinkle [flags] on top like glitter. ✨

---

✨ DESCRIPTION ✨

Upgrades one or all installed platforms to the latest version. that's the vibe. that's the mission. you point it at stuff, it makes that stuff shiny and new. 🌈

---

✨ OPTIONS ✨

• -h, --help[=false] — help for upgrade. it's the "wait what does this do again" button, no shame, we all press it. 🫶
• --run-post-install[=false] — Force run of post-install scripts (if the CLI is not running interactively). so like, if you're not sitting there in an interactive session, this forces those post-install scripts to actually run anyway.
• --run-pre-uninstall[=false] — Force run of pre-uninstall scripts (if the CLI is not running interactively). same deal but for the pre-uninstall scripts, and again only when the CLI isn't running interactively.
• --skip-post-install[=false] — Force skip of post-install scripts (if the CLI is running interactively). flip side: you are interactive, but you wanna skip the post-install scripts anyway. okay diva, skipping. 💀
• --skip-pre-uninstall[=false] — Force skip of pre-uninstall scripts (if the CLI is running interactively). interactive session? yes. pre-uninstall scripts? not today. skipped. 🙈

---

✨ OPTIONS INHERITED FROM PARENT COMMANDS ✨

these are the flags you didn't ask for but got anyway, and honestly they ate. 👑

• --additional-urls=[] — Comma-separated list of additional URLs for the Boards Manager. drop extra board sources in here, separated by commas. 🍓
• --config-dir="" — Sets the default data directory (Arduino CLI will look for configuration file in this directory). so the CLI goes hunting for your config file in this dir. 🔍
• --config-file="" — The custom config file (if not specified the default will be used). want a specific config file? say it here. don't? default it is. 💜
• --json[=false] — Print the output in JSON format. for when you want your data machine-readable and your scripts happy. 🤖
• --log[=false] — Print the logs on the standard output. logs, but make them loud, right there on stdout.
• --log-file="" — Path to the file where logs will be written. logs, but make them a file instead. 📁
• --log-format="text" — The output format for the logs, can be: text, json. pick your fighter.
• --log-level="info" — Messages with this level and above will be logged. Valid levels are: trace, debug, info, warn, error, fatal, panic. turn the volume up or down accordingly. 🔊
• --no-color[=false] — Disable colored output. for monochrome girlies or pipes that can't handle the rainbow. 🌈🚫

✨ EXAMPLE ✨

here's how the cool kids do it:

# upgrade everything to the latest version
debian/build/bin/arduino-cli core upgrade

# upgrade arduino:samd to the latest version
debian/build/bin/arduino-cli core upgrade arduino:samd

first one: everything gets upgraded, no notes, main character energy. second one: just arduino:samd gets the glow-up, because sometimes you're loyal to one platform and that's valid. 🎀
