PIBOOTCTL-SET(1)

✨ pibootctl-set(1) ✨

okay bestie, so this is a page from the pibootctl manual 💅 and it's literally all about the pibootctl set command. no cap, it's giving "change ur Pi's boot settings" energy and honestly? iconic.

🌸 NAME 🌸

pibootctl-set — it's a page in the pibootctl manual, bestie. that's the whole vibe. 🎀

---

🦋 SYNOPSIS 🦋

pibootctl set [-h] [--no-backup] [--all | --this-model | --this-serial]
              [--json] [--yaml] [--shell]
              [name=[value] [name=[value] ...]]

---

💖 DESCRIPTION 💖

so like, set changes the value of one or more boot configuration settings. that's it, that's the whole thing ✨

and here's the cute part: if u wanna reset a setting back to its default, u just omit the new value. literally just don't give it one. the way that works is so clean honestly. 🫶

---

✨ OPTIONS ✨

• name=[value] — drop one or more settings to change right there on the command line 💅 and if u wanna reset a setting to its default, just leave the value off. no value, no problem.
• -h, --help — shows u a lil brief help page for the command. ur lil cheat sheet fr fr 📖
• --no-backup — pls don't take an automatic backup of the current boot configuration if one doesn't exist already. bold move, bestie 😭
• --all — set the settings u named on all Pis this SD card is used with. this is the default context, so if u don't say anything, this is what u get 👑
• --this-model — set the settings for this model of Pi only. specific queen behavior 💅
• --this-serial — set the settings for this Pi's serial number only. like, just this one physical Pi. main character energy, honestly 🌟
• --json — use JSON as the input format 🧚
• --yaml — use YAML as the input format 🌈
• --shell — use a var=value input format suitable for the shell 🐚

---

💅 USAGE 💅

so u can use set right at the command line to update the boot configuration, like:

$ sudo pibootctl set video.overscan.enabled=off
Backed up current configuration in backup-20200309-230959

and note — if no backup of the current boot configuration exists, a backup is automatically taken (unless u passed --no-backup, obviously). no cap. 📸

u can change multiple settings all at once too, and reset settings to their default value by omitting the new value after the = sign:

$ sudo pibootctl set --no-backup serial.enabled=on serial.uart=

see how serial.uart= has nothing after the =? yeah. reset. slay. ✨

by default, settings get written into an [all] section in config.txt, which means they apply everywhere the SD card gets moved. but bestie, u can opt to make settings specific to the current model of Pi, or even the current Pi's serial number:

$ sudo pibootctl set --this-serial camera.enabled=on gpu.mem=128

and in that case an appropriate section like [0x123456789] will be added, and the settings get written under there. very demure, very specific. 🎀

and for anyone out there building an interface on top of pibootctl (devs, i see u 👀), JSON, YAML, and shell-friendly formats can also be used to feed new values to the set command:

$ cat << EOF | sudo pibootctl set --json --no-backup
{"serial.enabled": true, "serial.uart": null}
EOF

quick vibe check: that backup thing is automatic unless u say --no-backup, so don't be surprised when a backup-... file just appears. it's not haunted, it's a feature 🫶
