$ which rename /usr/bin/rename $ dpkg -S $(!!) dpkg-query: no path found matching pattern /usr/bin/rename
I normally don't install commands by hand in
/usr/bin, and on the other machines I have access to,
rename is installed as well. My first suspicion was that this command was copied there in some post-install step of some package.
Then I did an
ls -l /usr/bin/rename and found that the
rename command did happen to be a link. I tried
dpkg -S on the link target (
dpkg -S /etc/alternatives/rename did not give a package name either.
After some further searching I found that real executable target of that link chain is
/usr/bin/prename and there is a bug report for
dpkg -S behaviour of not following symlinks. That report is from 2003 and I could not find any option to follow symlinks for
dpkg and that issue doesn't seem likely to be resolved.
How can I easily find the package that contains the "real" executable in case the command is a symlink?
