{
vi} = 2 {vim} = 3 {v=vim} = 5I'd need to run vi at least 5 times to have a net gain in saving keystrokes. I'm typically in effemerial systems created by the users of our env, so rarely am I going to gain those strokes back
But also, why am I trying to apply logic to this? I'll often cat a file before editing it. This shit is just illogical idiosyncrasies I've picked up over the years. I'm probably creating posthoc justifications for insane things I do cause it's hard to override muscle memory
effemerial is new to me
Here's a link I found that might be good if you are interested in more:

There are different levels of effemeriality. The simplest example I use daily would be an autoscaling group in AWS. Especially if you use Spot Instances to save money, thi gs may scale in and out whenever.
So if a development team creates a new autoscaling group and I need to get into an instance to test something, unless I add stuff to their IaC, I'm stuck with their configuration. I need to assume that every time I ssh into one of those instances, it's a brand new instance. But it'd be a big challenge for me to go to their repo and make a PR to alias a command whenever an instance in that resource is created
Stuff can be even more temporary if it's something like an ECS task which creates a container with a read only filesystem only when a task is needed to be done. But I don't want to get too deep in the weeds (or deeper than I already have)
terraform workspace will at least stick around for a while so you might be in and out of the same system multiple times.
