I am a linux user through and through. Desktop, server, vms, containers,
everything except my phone is linux. With this I spend a lot of time in the
terminal, and have been a long time user of `!!` to rerun the last command, but
with the ability to tack something on at the beginning or end.

TIL about `fc`, which opens the last command in your shell history in your
`$EDITOR` or pass in your editor `-e nvim`.

[man fc](https://manned.org/fc)

## Rcap of how !! works

`!!` pronounces `bang bang` and will run the last command in your history.

``` bash
ls -l

!! | wc -l
# ls -l | wc -l

sudo !!
# sudo ls -l | wc -l

!!:s/-l/-l \/tmp
# sudo ls -l /tmp | wc -l
```

## `fc` enters the chat

Now making complex edits in your shell can be a bit of a chore, so `fc` moves
this work to your `$EDITOR`.

``` bash
fc
```

This pops open your $EDITOR with the last command in your history.

``` vim
sudo ls -l | wc -l
```

## Shell History

`fc` shows up in shell history, but `!!` does not, `!!` gets replaced by the
command that it becomes.

## Up Arrow

yaya yaya, I know you can also `up-arrow c-e`, but what fun is that, it's barely a
flex. `fc` just looks big brained and like you really know what you are doing.
