Echo equivalent in PowerShell for script testing

Question

I would like to output variables and values out in a PowerShell script by setting up flags and seeing the data matriculate throughout the script.

How would I do thi

Answer 1

The Write-host work fine.

$Filesize = (Get-Item $filepath).length;
Write-Host "FileSize= $filesize";

Answer 2

I don't know if it's wise to do so, but you can just write

"filesizecounter: " + $filesizecounter

And it should output:

filesizecounter: value

Answer 3

PowerShell has aliases for several common commands like echo. Type the following in PowerShell:

Get-Alias echo

to get a response:

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Alias           echo -> Write-Output

Even Get-Alias has an alias gal -> Get-Alias. You could write gal echo to get the alias for echo.

gal echo

Other aliases are listed here: https://docs.microsoft.com/en-us/powershell/scripting/learn/using-familiar-command-names?view=powershell-6

cat dir mount rm cd echo move rmdir chdir erase popd sleep clear h ps sort cls history pushd tee copy kill pwd type del lp r write diff ls ren

Answer 4

It should also be mentioned, that Set-PSDebug is similar to the old-school echo on batch command:

Set-PSDebug -Trace 1

This command will result in showing every line of the executing script:

When the Trace parameter has a value of 1, each line of script is traced as it runs. When the parameter has a value of 2, variable assignments, function calls, and script calls are also traced. If the Step parameter is specified, you're prompted before each line of the script runs.

Answer 5

PowerShell interpolates, does it not?

In PHP

echo "filesizecounter: " . $filesizecounter 

can also be written as:

echo "filesizecounter: $filesizecounter" 

In PowerShell something like this should suit your needs:

Write-Host "filesizecounter: $filesizecounter"

Answer 6

Write-Host "filesizecounter : " $filesizecounter
