While I was working with a lot of reports, it made sense to use a standard file name for all the files. This was an afterthought, so it required me to rename the files. I was hoping Ubuntu Nautilus had this option, but for my current version -16.04- it doesn’t. That feature is expected to land in 17.04. in the meantime you can install nautilus-renamer which offers the same feature.
Just download the .deb package from the nautilus-renamer launchpad page and install it with
sudo dpkg -i nautilus-renamer_4.0-quantal_all.deb sudo apt install -f killall nautilus
Then, just open a nautilus window and select a bunch of files, right click and select ‘rename…’ or just press F2.
