TALER-MDB-DISPLAY(1)

📦 version 1.3.0, in nixos 26.05, nixpkgs unstable

💅 TALER-MDB-DISPLAY(1) — the group chat version 💅

okay so bestie, welcome to taler-mdb-display, part of the GNU Taler family of manpages 🎀 this little icon is a command-line tool and honestly? it does one (1) thing and it does it flawlessly. we love a focused queen.

✨ SYNOPSIS ✨

taler-mdb-display [-c FILENAME] [-h] [-i**_|_--backlight-invert**] [-L
_*LOGLEVEL* | --log=LOGLEVEL] [-l _*FILENAME* | --logfile=FILENAME]
[-v | --version]
ngl the synopsis above is giving "sent from my phone at 2am" energy with those stray * and _ marks — that's literally how the original page renders it, so I'm not touching it. respect the artifact 💀

🌸 DESCRIPTION 🌸

so taler-mdb-display is a command-line tool that simply toggles the backlight setting. that's it. that's the whole personality. ✨ depending on your hardware, the -i option may be the thing that turns the light on or off, and then — plot twist — you can get the opposite effect by just… not passing -i. main character energy: it does the opposite of whatever -i does, on purpose, always. 🔥

its options are as follows, bestie:

  • -c FILENAME, --config=FILENAME — use the configuration and other resources that this command needs to operate from FILENAME. everything it needs, it gets from there 🫶
  • -i, --backlight-invert — invert the bit for turning on/off the backlight. so without the option, the tool will do the opposite. yes, this is a bit of a mind game, no cap 💅
  • -h, --help — print short help on options. your little cheat sheet 🎀
  • -L LOGLEVEL, --log=LOGLEVEL — configure logging to use LOGLEVEL. tell it how chatty to be ✨
  • -l FILENAME, --logfile=FILENAME — configure logging to write logs to FILENAME. receipts, but on disk 🦋
  • -v, --version — print version information. (the original page writes this one as –version with a fancy en-dash instead of a double hyphen — iconic little typo moment, but the option is --version 😭)
