The Big Book of PowerShell Error Handling

by Dave Wyatt


Despite the title, this is actually a very small, concise book designed to help you understand how PowerShell generates and deals with errors. It’s also designed to help you build the best possible error handling for your own scripts and functions, in just a few short lessons.

Check for Updates! Our ebooks are often updated with new and corrected content. We make them available in three ways:

GitBook and LeanPub have slightly different PDF formatting output, so you can choose the one you prefer. LeanPub can also notify you when we push updates. Our main GitHub repo is authoritative; repositories on other sites are usually just mirrors used for the publishing process. GitBook will usually contain our latest version, including not-yet-finished bits; LeanPub always contains the most recent “public release” of any book.
