Lastly, I made a decision to create a customized perform that may examine two textual content strings. I referred to as the perform Evaluate-TextStrings.
Syntaxes
The Evaluate-TextStrings perform has two syntaxes. Right here they’re…
Evaluate-TextStrings [-FirstTextString] <String[]> [-SecondTextString] <String> [[-DisplaySimilar]] [[-DisplayDifference]] [<CommonParameters>]
Evaluate-TextStrings [-FirstTextString] <String[]> [-SecondTextString] <String> [[-DisplaySimilar]] [[-DisplayDifference]] [[-OutFile]] [[-Path] <String>] [<CommonParameters>]
You employ the primary syntax to show the results of the command on the PowerShell console. Quite the opposite, you should utilize the second syntax to ship the output of the command to a textual content file.
To study extra, learn the subsequent part…
Parameters
To successfully use the PowerShell perform, Evaluate-TextStrings to check two textual content strings, it’s essential to perceive the parameters of the perform.
Within the desk under, I’ve defined all of the parameters and tips on how to use them.
| Parameters of Evaluate-TextStrings | Feedback/Notes |
|---|---|
| FirstTextString | This parameter is used to specify the primary textual content string you wish to examine. It’s a required parameter |
| SecondTextString | Use the SecondTextString to specify the second textual content string you wish to examine in PowerShell. Just like the FirstTextString parameter, SecondTextString is a required parameter |
| DisplaySimilar | The DisplaySimilar parameter is a Change parameter. It implies that it doesn’t require any enter. You simply have to specify the parameter. So, once you specify the DisplaySimilar parameter, Evaluate-TextStrings shows the elements of each texts which might be related or the identical. |
| DisplayDifference | That is additionally a Change parameter. In the event you specify the DisplayDifference parameter, Evaluate-TextStrings shows the texts which might be totally different within the texts strings you’re evaluating |
| OutFile | You need to use this parameter to ship the output of Evaluate-TextStrings to a textual content file. The OutFile parameter is a Change; so it doesn’t require enter. The parameter is optionally available |
| Path | Use the Path parameter to specify the trail to save lots of the textual content file. If the OutFile parameter is specified however the Path parameter shouldn’t be specified, Evaluate-TextStrings will save the textual content file within the person’s temp folder, normally situated in [Windows Install Drive]CustomersAppDataLocalTempCompareString. In any case, the identify of the textfile is within the format dd-MM-yyyy.txt
Alternatively, in the event you specify a path with the Path parameter, Evaluate-TextStrings will save the textfile in $Path + “CompareString” |

Now that you recognize the syntaxes and parameters of Evaluate-TextStrings, it’s time to see some examples.
