@Christoph one of my machines is at 1028 days but still only a single exclamation mark... sadge... 😢

The produced ttf misses metadata from the input sfd like copyright, weight, version. Those are filled when doing the conversion in the GUI. How do I keep these fields when converting via the command line?

Note that this only works in situations where the input is finite. Oftentimes I find myself desiring a portable replacement for process substitution especially in cases where a process generates content on demand or dynamically, meaning you cannot even create a temporary file. One such scenario is sort --random-source. In these cases, this approach will not work but instead enter an infinite loop.

Thank you, that was a very educative read! I've adjusted my answer accordingly and will go through my own shell scripts fixing these instances.

"Do not use [0-9] which often matches a lot more" -- in which shell? Why? Where did you see this behavior in the wild?

It should be noted that despite its name and despite it not being mentioned anywhere in its manual page, lsblk will also list lvm2 volumes, luks partitions and so on.

@X.LINK do you have a source for your claims?

Since the original question mentioned that this is for a script, the -P option to lsblk might be of interest which prints the desired values in a way that can be eval-ed in a shell script.
