Command

What

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 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 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.
