Thank you for your kind, patient, reply Phelype. I do not see the
output that you see, so something on my system must be wrong (due to
my fault). Perhaps giving debugging output from commands can help to
find the cause of my mistake. Here are some relevant I think commands:

$ sudo /opt/texbin/tlmgr install latex-bin-dev
[sudo] password for xuwang:
tlmgr: package repository http://www.math.utah.edu/pub/tlpretest (verified)
tlmgr install: package already present: latex-bin-dev

$ which -a pdflatex-dev
/opt/texbin/pdflatex-dev
$ file /opt/texbin/pdflatex-dev
/opt/texbin/pdflatex-dev: symbolic link to pdftex

However, I did not make the above symbolic link. Not sure where it's a
result from.

Thus not a surprise:

$ pdflatex-dev
This is pdfTeX, Version 3.141592653-2.6-1.40.22 (TeX Live 2021)
(preloaded format=pdflatex-dev)
 restricted \write18 enabled.
**^C
$ pdflatex
This is pdfTeX, Version 3.141592653-2.6-1.40.22 (TeX Live 2021)
(preloaded format=pdflatex)
 restricted \write18 enabled.


Following is output from tlmgr update. I doubt it is relevant but I
give in case it is:

$ sudo /opt/texbin/tlmgr update --all
tlmgr: package repository http://www.math.utah.edu/pub/tlpretest (verified)
