## What
:::caution powershell
While powerful, it tends to take a lot of time executing the command on **PowerShell**.
Even with `noprofile` it's noticeably slower compared to `sh`. It's advised to look at using
[environment variables][env] when using PowerShell.
:::
Command allows you run an arbitrary shell command. Be aware it spawn a new process to fetch the result, meaning
it will not be able to fetch session based context (look at abusing [environment variables][env] for that).
When the command errors or returns an empty string, this segment isn't rendered.
You have the ability to use `||` or `&&` to stitch commands together and achieve complex results. When using `||`
the first command that returns a string will be used (or none when they all fail to produce output that's not an
error). The `&&` functionality will join the output of the commands when successful.
