Ubuntu 16.04

Syncthing is one of the best tools for keeping folders synchronized across the internet. However, for one or the other reason, it occasionally stops to work on my Ubuntu 16.04 and because I use it in a "set it and forget it" fashion, I also forget how to check that it is operational.
Make it start automatically at boot time (as a system service): systemctl enable syncthing@username.service
Start the service: systemctl start syncthing@username.service

Under Ubuntu 16.04, the ScanSnap iX100 is not supported yet by the sane package. In order to get it working, you need to install the ppa from Rolf Bensch:

sudo add-apt-repository ppa:rolfbensch/sane-git
sudo update
sudo upgrade


The default command line application for batch renaming files in Ubuntu 16.04 is called "rename":
rename 's/tk98i_/wt_tk98_/' *.tif
It uses Perl regular expressions with and the s/old/new/ syntax. The example above renames all files with the .tif extensions and replaces the th98i_ expression with wt_tk98_.
