OS? (2 comments)

alx‭ wrote 6 months ago

Which OS are you using? Is the program installed through the OS package manager? In Debian you can check the package that provides a file with dpkg -S:

$ dpkg -S /usr/bin/groff 
groff-base: /usr/bin/groff

And then search for the package version with dpkg -l:

$ dpkg -l groff-base | grep groff-base
ii  groff-base     1.23.0-4     amd64        GNU troff text-formatting system (base system components)
