As a first step in re-installing MacPorts (long story), I ran $ sudo port -fp uninstall installed
according to the instructions at https://guide.macports.org/#installing.macports.uninstalling Before uninstalling, the Finder indicated that /opt/local contained 21 GB. After, /opt/local was nearly empty, as expected. I completed the steps indicated to complete the uninstallation. I happened to check the “Used” quantity, as indicated by Finder on Get Info on my boot volume (which contained /opt/local) before uninstalling, and again after uninstalling. I expected to see this quantity reduced by 21 GB. But there was no change! Why was the “Used” number unchanged after deleting 21 GB? Thanks. Jerry
