fw_setenv(8)

✨ fw_setenv ✨

okay bestie, welcome to the manual page for fw_setenv from the System Manager's Manual — it's a whole mood and it's literally your lil' key to poking the U-Boot bootloader's environment 💖

🌸 NAME 🌸

fw_setenv — the tool for modifying the environment for the bootloader U-Boot 🫶

🎀 SYNOPSIS 🎀

fw_setenv name [ value ]

🦋 DESCRIPTION 🦋

so here's the tea, bestie: fw_setenv is a simple tool for modifying the environment for the bootloader U-Boot. The variable name gets updated to hold value if it's already set in the environment — and if it's not already there? it just gets created and set. no cap, it does both 💅

if you only pass the name argument and nothing else, the corresponding variable gets deleted. gone. poof. 🙈

and here's the iconic lore: this version of fw_printenv stems from libubootenv and does not hold a built-in default environment. nope, not a vibe it keeps. instead, the default environment is read from a file. that's just how she operates ✨

💅 OPTIONS 💅

• -h — print a help message 🥺
• -c, --config <filename> — configuration file (the old fw_env.config, iykyk)
• -f, --defenv <filename> — default environment if no one found 👀
• -V — print program's version ⭐
• -s, --script <filename> — read variables to be set from a script 🎬

🌈 FILES 🌈

• /etc/fw_env.config — Configuration file for fw_setenv. this is the default value of the --config option 🍓
• /etc/u-boot-initial-env — Default U-Boot environment. this is the default value of the --defenv option 🧚
