I tend to switch Linux distributions quite often. Consequently, I tend to have this process down to a fine art and it doesn’t take me that long. The most time consuming element is ensuring the necessary backups are in place. However, you normally find some package or configuration option you forgot about and my recent switch from Arch Linux to Fedora 29 and back again unearthed a strange problem with the Dovecot IMAP server I hadn’t encountered before.

Occasionally, I have to search lots of files for a pattern. It was only recently I discovered the wonderful silver searcher utility which saves me a lot of time. To install ‘ag’ on Fedora, use the following (which isn’t entirely obvious or intuitive if you’re used to typing ‘ag’). # sudo dnf install the_silver_searcher I believe there is an Emacs interface which would save me even more time. $ time ag 'sql statement execute time' ~ real 0m0.
