bash script for $* loop accept command line with spaces in wildcard file names at DuckDuckGo

Posted by jpluimers on 2026/05/05

Back when I wanted a more universal solution [Wayback/Archive] bash script for $* loop accept command line with spaces in wildcard file names at DuckDuckGo I got into a mess of tips that either did not work at all, or were very convoluted.

As back then I only needed a one-time solution, I just listed the filenames with ls into a text file, did some sed and editing steps, then had each file execute in a separate step. Low tech, non-repeatable when new files appeared, but good enough.

In case I want to go for a more universal solution, below are some links to investigate further. Will likely take me hours, so most of the time this is not worth it. Maybe the subshell plus $IFS (Input Field Separators) is a good start, though it gives me a feeling that in the future it will break something else that was expecting a default $IFS value, as is using while read loop. Both types of solutions feel too convoluted. Same for the array solution below.

I might have just been spoiled with PowerShell piping objects instead of strings having made life so much easier.

How to adapt a DucoBox Silent system to make it use Open Source hardware and software for keeping CO2 and humidity levels at healthy levels

Posted by jpluimers on 2026/05/05

The hackability of the [Wayback/Archive] DucoBox Silent “smart” home ventilation box with [Wayback/Archive] Flamingo-tech/Open-AIR: Open source system for home ventilation and control via HA based open hardware was shown by [Wayback/Archive] Jilles Groenendijk (@jilles_com) / Twitter with open source products from [Wayback/Archive] Browse products by TheFlamingo on Tindie in this Tweet:

[Wayback/Archive] Jilles Groenendijk on Twitter: “I bought a duco.eu/uk/products/mechanical-ventilation/ventilation-units/eng-ducobox-silent ripped out all its proprietary electronics and replaced it with open source hardware: tindie.com/stores/theflamingo Now I am able to measure temp/humidity/pressure/co2 of all the connected rooms. And switch the ventilation on each individual area.”

The above Tweet contains useful pictures and a video which I have added below the post signature because they so well show the placement of the open source hardware. Same for the pictures from:

The whole setup integrates well with Home Assistant.
