I found a couple of scripts, but I generally disliked them, as they all used “cat” or “wc”, which is quite heavy when you have a couple of million lines. That would mean spending a lot of time looping the same log file. Instead we can tail it. text/html 2016-08-09T14:00:12+00:00 Anonymous (anonymous@undisclosed.example.com) https://biggi.dk/dokuwiki/doku.php/bash/disable_synaptics_coasting?rev=1470751212&do=diff To disable the very annoying feature that keeps scrolling even after you let go of the touchpad, run the following command: synclient CoastingSpeed=0 Instead of “Coasting”, I vote that the feature is renamed to “Drunk emulator”.

As always I started out doing a small run'n'delete-script, but I decided to go all in and make it a bit user friendly and all that. The script grabs current users and packs them in a query. Then it dumps all the db's with mysqldump and imports it on the other machine via. SSH. Run the script on the machine you want to move FROM. Make sure that sshpass, mysqldump and pigz/gzip is installed.
