ForEach-Object

ForEach-Object

When ForEach-Object is used in a pipeline with other commands and its scriptblock causes an error then the error info tends to be not clear.

ForEach-Object can be replaced with .{process{...}}. The latter works faster and does not obfuscate information of potential errors.

Scripts

• Oops.ps1 simulates a problematic script, it just throws an error.
• test1.ForEach-Object.bad.error.info.ps1 uses ForEach-Object and shows bad error information.
• test2.ScriptBlock.good.error.info.ps1 uses .{process{...}} and shows clear error information.
• test3.measure.performance.ps1 shows that .{process{...}} is much faster than ForEach-Object.
