12 min read • Intermediate

try catch finally is an atomic PowerShell topic inside Errors & Diagnostics. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what try catch finally changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.

Topic-specific example

powershell-06-01-try-catch-finally.ps1

powershell Try It Live

try { throw "boom" } catch { "caught" } finally { "cleanup" }

Edge case / engineering note

Exercise both the success path and the failure path; verify what is caught, propagated, or cleaned up rather than only checking printed output.
