I think I misunderstood you, when you said “manually”, to mean as a human intervention in the process. What you’re showing here is an extra processing step, but I wouldn’t call that manual. Just want to clear that up, but I’m still down to play.
Instead of three greps, you could use one sed or awk. I don’t think there’s anything particularly wizardly about awk, and it would be a lot less cryptic, to me, than this chain of greps.
But a much better idea would be to use sensors -j to get json output, intended for machine reading, and pass that to jq. Since I don’t have the same sensors output as you, I’m not sure exactly what that would be, but I am guessing probably something like:

Yes, it’s not manual by the dictionary definition, but it is an extra step. This is another meaning of manual in my particular bubble [Edit: that I didn’t think to specify].

This is my initial point, exactly. Dealing with objects is way easier than using the ‘default’ line-wise processing. Only Powershell made that the default, while in Linux you need to hope that utilities have an option to toggle it on – and then also have jq installed to process the objects.
I look forward to seeing how you would do this in PS. As I said previously, I don’t know it at all, so I’m not sure what you’re comparing this to.
[Edit, since I forgot to answer your main point:] I don’t program in PS. I don’t like the verbosity. But I do think MS has a point in pushing objects as the prime unit in processing instead of lines.
For instance: Get the temperature of the “Composite” sensor from this output:
$ sensors k10temp-pci-00c3 Adapter: PCI adapter Tctl: +37.1°C BAT1-acpi-0 Adapter: ACPI interface in0: 16.07 V curr1: 1.80 A amdgpu-pci-0500 Adapter: PCI adapter vddgfx: 1.46 V vddnb: 918.00 mV edge: +35.0°C slowPPT: 1000.00 uW nvme-pci-0200 Adapter: PCI adapter Composite: +28.9°C (low = -5.2°C, high = +79.8°C) (crit = +84.8°C) acpitz-acpi-0 Adapter: ACPI interface temp1: +37.0°C (crit = +120.0°C)Without a cryptic awk incantation that only wizards can understand, that would be:
sensors | grep Composite | grep -Po 'Composite:.*?C' | grep -Eo '[[:digit:]]{1,2}\.[[:digit:]]'I think I misunderstood you, when you said “manually”, to mean as a human intervention in the process.
