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 this?
For example, what would be the PowerShell equivalent to the following PHP code?
echo "filesizecounter: " . $filesizecounter
This question is related to
powershell
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"
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 of1
, each line of script is traced as it runs. When the parameter has a value of2
, variable assignments, function calls, and script calls are also traced. If theStep
parameter is specified, you're prompted before each line of the script runs.
The Write-host work fine.
$Filesize = (Get-Item $filepath).length;
Write-Host "FileSize= $filesize";
Powershell has an alias mapping echo to Write-Output
, so:
echo "filesizecounter : $filesizecounter"
echo is alias to Write-Output although it looks the same as Write-Host.
It isn't What is the difference between echo and Write-Host in PowerShell?.
echo is an alias for Write-Output, which writes to the Success output stream. This allows output to be processed through pipelines or redirected into files. Write-Host writes directly to the console, so the output can't be redirected/processed any further.
Try Get-Content .\yourScript.PS1
and you will see the content of your script.
also you can insert this line in your scrip code:
get-content .\scriptname.PS1
script code
script code
....
By far the easiest way to echo in powershell, is just create the string object and let the pipeline output it:
$filesizecounter = 8096
"filesizecounter : $filesizecounter"
Of course, you do give up some flexibility when not using the Write-* methods.
Write-Host "filesizecounter : " $filesizecounter
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
I don't know if it's wise to do so, but you can just write
"filesizecounter: " + $filesizecounter
And it should output:
filesizecounter: value
