you might want to purge the debian installation of tide sudo apt-get purge xtide
otherwise there might be config files lingering around that confound your new xtide installation. ('apt-get remove' removes the software, but leaves configurations and data behind. 'apt-get purge' is more aggressive, and removes the configurations too.) or you could do sudo-apt-get install xtide then put your new harmonics file somewhere, say /opt/tide/harmonics-dwf-20181227-free.tcd then make the shell script at /opt/tide/tide.sh: #!/bin/sh HFILE_PATH=/opt/tide/harmonics-dwf-20181227-free.tcd tide "$@" then set the permissions: sudo chmod 755 /opt/tide/tide.sh then use it in your forecast configuration: prog = /opt/tide/tide.sh that way you can have both - the old xtide and the new xtide, so you can do direct comparisons from the command line. m -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
