Syncthing

Wed, 24 Jan 2018 00:00:00 +0000

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.serviceStart the service: systemctl start syncthing@username.serviceCheck the status: systemctl status syncthing@username.serviceThe URL of the GUI: https://127.0.0.1:8384 However, the above solution does not work well if e.g. the files to syncronize reside on an encrypted folder which is mounted only after the user has logged in (e.g. in Ubuntu 16.04, there was the possibility to encrypt the user folder, which was only unlocked during user login). Alternatively, one can run the service as a “user service” like this:cp /usr/lib/systemd/user/syncthing.service ~/.config/systemd/user/systemctl --user enable syncthing.servicesystemctl --user start syncthing.serviceSyncthing seems to regularly loose a file called “.stfolder”, which is supposed to be in the root of any shared folder (or it gets converted into a folder). For me the problem gets usually fixed by simply recreating that (empty) file (and deleting the folder with the same name if it exists).

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-gitsudo updatesudo upgrade

Batch renaming files on the command line

Tue, 28 Jun 2016 00:00:00 +0000

The default command line application for batch renaming files in Ubuntu 16.04 is called “rename”:rename 's/tk98i_/wt_tk98_/' *.tifIt 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_.Here are some more examples: http://tips.webdesign10.com/how-to-bulk-rename-files-in-linux-in-the-terminal
