Public bug reported: TL;DR In a fresh install rename(1) is missing, but its manual page is there. Upon installing rename, another rename is installed, replacing the man page. Further upon removing the newer rename package, both the executable and the man page are gone. The system still insists that util-linux is installed and at the latest version.
In a fresh Ubuntu-24.04 system, the rename function is missing. However there is a manual page for rename(1), which comes installed with the system, which says is part of the util-linux package. Upon calling rename(1), the system surprisingly says: Command 'rename' not found, but can be installed with: sudo apt install rename Which is weird because util-linux is installed (and at its latest version). But after installing rename following this suggestion, the rename utility is now from a Perl package, and the installed manual page is now for rename(1p), overwriting the previous man page. When the rename package is removed, no man page remains for rename(1). Not sure what the bug is: - rename(1) should have been installed and available in a fresh system? - both rename(1) and its manual page should not be available in a fresh system? (and only installed on demand) - the rename perl package should not overwrite a previously existing man page from another package? This has been reported before unoffically: https://askubuntu.com/questions/1095759/rename-command-not-found-when-running-a-script How to reproduce: 1) make sure you start with a fresh system lsb_relase - a No LSB modules are available.
