I then edited "test.txt", inserted a newline between the `4` and
`5`, and saved the file. I reran the same command as before:
Head be default takes 10 lines. So you'll need a couple more newlines.
By default, yes, but he explicit specifies '-c 10' overriding the
default, and tr will have removed the newlines before head gets them.
Can you actually demonstrate the bug you claim to be there? (I'm not
sure no kind of nastiness can hide in those pipes)

PS. The lack of a way to choose passwords without/with only certain
characters is one of the reasons I still haven't switched to pass (using
pwsafe), even though I like the project.

I'm talking about the first head, not the second. This command gives you
12345 when you expected 12345678.
echo '12345
67890' | head | tr -dc '0-9 | head -c 8 && echo
A fixed command looks like this (drop the unnecessary head)
tr -dc 'A-Za-z0-9!"#$%&'\''()*+,-./:;<=>?@[\]^_`{|}~' </dev/random |
head -c 32 && echo
