What are some good short or medium-length resources for refreshing PowerShell basics?

Using PowerShell regularly is probably the easiest way to become comfortable with it. Your familiar Bash commands are still available as programs on the PATH, so you can use them while gradually learning PowerShell syntax and equivalents. Start with a few core tools: use `help ` with options such as `-Examples` or `-Detailed`, use `Get-Command` (or `gcm`) with wildcards to discover commands like `*csv*` and `*json*`, and practice composing pipelines with filtering, iteration, and property selection. Once those patterns click, PowerShell becomes much easier to use. It’s also useful to learn the basics of arrays such as `$array = @()` and dictionaries such as `$dict = @{}`.

The built-in about_* help topics are worth working through. Together, they cover a huge amount of PowerShell’s fundamentals and function almost like a detailed reference manual. Also, you don’t have to change terminal applications—PowerShell can run inside whichever terminal you already prefer.

PowerShell in a Month of Lunches is a solid choice. It breaks the material into manageable lessons, so you can make steady progress without needing huge study sessions.

Try PSKoans if you prefer learning by doing. It gives you small exercises that gradually become more challenging, and most of them are short enough to finish during a lunch break.
