The manpage (and pinfo tr too) is, shall we say, completely lacking

Plus, you probably have a program called dos2unix installed...
Oops, I should have read past the word 'legacy' which must not have
meant what I thought.
tr '\r' '\n'
should work.
More like:
cat input-filename | tr '\r' '\n' >output-filename
Not so? tr is a filter.
It reads stdin and writes stdout, like most unix command line programs.
The shell will connect those to whatever you want with |'s or
<>'s. Using cat with a pipe is a waste of a process, though. tr can
read it's own input just as well with <input-filename.
Quite true, but I remember a remark in one of the classic Unix papers to
the effect that people somehow found the 'cat foo | ' syntax more
natural.
I suppose you get used to using cat when there are multiple input files
that you want to combine.
