PowerShell - WinGet - Compare Available Package Version to Currently installed-CodePudding

Currently working with WinGet to improve application deployment lifecycle within Intune. I am looking at deploying a detection script that checks for the installed version daily, then triggers the remediation if there is an available update.

Doing something as simple as:

winget list --name 7-Zip

will return as follows:

Name              Id        Version Available Source
----------------------------------------------------
7-Zip 19.00 (x64) 7zip.7zip 19.00   22.01     winget

Within Powershell, is there a way we can check and compare the Available "column" to the Version "column", and return an exit 0 or exit 1?

Thanks in advance

Why not use

winget upgrade

it will return available upgrades

Name                                                      Id                                    Version          Available     Source
Google Chrome                                             Google.Chrome                         103.0.5060.53    104.0.5112.81 winget
Microsoft Edge                                            Microsoft.Edge                        103.0.1264.49    104.0.1293.47 winget

If all you need to know is whether or not an upgrade is available, to be reflected in the script's exit code:

The following reports exit code 1 if an upgrade is available, and 0 otherwise, relying on an Available column header only being present if an upgrade is available:

exit [int] (winget list --name 7-Zip | Select-String '\bVersion\s Available\b' -Quiet)

If you also want to report the installed vs. the latest available version, more work is needed:

$name = '7-Zip'
$lines = winget list --name $name
if ($lines -match '\bVersion\s Available\b') {
  $verinstalled, $verAvailable = (-split $lines[-1])[-3,-2]
  [pscustomobject] @{
    Name = $name
    InstalledVersion = $verInstalled
    AvailableVersion = $verAvailable
  }
  exit 1
} else {
  Write-Verbose -Verbose "No upgrade for $name available."
  exit 0
}

The above outputs something like the following if an upgrade is available; the exit code is set as in the first command:

Name    InstalledVersion AvailableVersion
----    ---------------- ----------------
7-Zip   9.0.30729.4148   9.0.30729.6161

Alternatively, if it's acceptable to blindly try to upgrade:

winget upgrade --name 7-Zip --silent
# If $LASTEXITCODE contains -1978335189, an upgrade was NOT available.
