# caveats: will choke if either arguments contain a forward slash | |
# notes: will back up changed files to *.bak files | |
ag -0 -l $1 | xargs -0 perl -pi.bak -e "s/$1/$2/g" | |

After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work. | |
The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0." | |
Database files have to be updated before starting the server, here are the steps that had to be followed: | |
# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default | |
brew unlink postgresql | |
brew install postgresql@9.6 | |
brew unlink postgresql@9.6 | |
brew link postgresql |

There are lots of different how-tos out there for automatically launching VMs using VirtualBox on MacOS. Most of them focus on older versions of VirtualBox or old versions of MacOS.
Tested using MacOS High Sierra 10.13.4 running VirtualBox 5.2.12. The guest OS is Fedora 28.
Following the instructions on the VirtualBox website (https://www.virtualbox.org/manual/ch09.html#autostart), copy the Virtualbox autostart plist template file to your system's LaunchDaemons folder.
