Hello,
I need to compare a percentage with a number. Since I'm really a beginner in powershell I don't know how I can do this.

When I write : if (pid.value -ge 20) it doesn't return the expected response.

Since pid.value returns a percentage (3.56% for example) I don't know how to compare it with a number
If I write pid.value ge 20% Will it work?
Or how can I do it otherwise?

Thanks in advance

Fiona

Do you have an example that anyone can run? PowerShell will not properly interpret percentages usually. You will have to transform the value into a regular number.

The example is the one I'm talking about above:

$value=$mypid.Value

if($mypid.Value -ge 20){

Write-Output "User $baduser is using $badprocess, PID: $key, with $value of resources!" | Out-File -filePath "$file_name.txt" -encoding UTF8 -append -noClobber
}

Like this,I don't get any error but my file contains values like 3.6 (but no 0.5%)

I thought about using a cast like this:
[float] $value -ge 20

But I don't know if it will work

[Edit] Just tried the float, doesn't work

Where does $mypid come from? Can you provide a complete example?

Sorry, here it is

$a=Get-WmiObject Win32_Processor | select LoadPercentage

# Snapshot des process en cours
$procBefore=Get-Process

# On attend un peu...
sleep -Seconds 1

# On reprend un snapshot
$procAfter=Get-Process


#Création du nom de fichier (log+date)
$date= Get-Date
$file_name = "{0}_{1:d2}_{2:d2}" -f $date.year,$date.month,$date.day


$dict = @{}

foreach ($p in $procBefore) {

# Correspondance des process avant et après
# stockée dans $z
$procAfter | where {$_.id -eq $p.id} -OutVariable z | Out-Null

$usage=(1-($p.WorkingSet64)/($z[0].WorkingSet64))
$usagepercent="{0:P2}" -f $usage

if ($usage -gt 0) {
$dict.Add($p.id, $usagepercent)
}
}

#Affichage de l'heure d'execution

$dict = $dict.GetEnumerator() | Sort-Object -Descending Value

foreach ($mypid in $dict) {

$baduser = (Get-WmiObject win32_process | where {$_.ProcessId -eq $mypid.Key}).getowner().User
$badprocess = (Get-WmiObject win32_process | where {$_.ProcessId -eq $mypid.Key}).Name
$key=$mypid.Key
$value=$mypid.Value

if($mypid.Value -ge "20%"){

Get-Date -displayhint time | Out-File -filePath "$file_name.txt" -encoding UTF8 -append -noClobber
Write-Output "User $baduser is using $badprocess, PID: $key, with $value of resources!" | Out-File -filePath "$file_name.txt" -encoding UTF8 -append -noClobber
}
}


exit(1)

Sorry, that's a bit too long for me to cycle through, so here's an example:
$perc=Get-WmiObject Win32_Processor | select -exp LoadPercentage
if($perc -gt 1){"Over 1"}

It all depends on what you're comparing, but likely you are comparing integer values.

To try this:
...
if($mypid.Value -ge "20%"){
...

You need to look at $mypid.value in detail. It could be an integer or a string. For example, it might be:
...
if($mypid.Value -ge 20){
...

Or maybe:
...
if([int]$mypid.Value -ge 20){
...

Ok thank you i'll try it
Since if($mypid.Value -ge 20) doesn't work I'll try the other one

[Edit] doesn't work either, it returns an error
