Azure Function Apps running with .NET 3.1 will go out of support on Dec 3 2022, something that the Azure Portal reminds users every time they visit their outdated functions. If like me, you have several functions, whouldn’t it be nice to be able to get a list of all the functions that should be updated?

A simple az functionapps list should do the trick, however the properties that provide this information are in one of the objects, siteConfig, which is not populated by the list command, and after searching for a while I found this solution for WebApps, the command for Function Apps is

az functionapp list --query '[].id' -o tsv | xargs | xargs -I{} bash -c "az functionapp config show --ids {} --query '[].[name, resourceGroup,linuxFxVersion, netFrameworkVersion]' --out table"

This command will list all the functions in the current subscription, provided proper permissions.

The output looks like this:

Column1	Column2	Column3	Column4
tseries-urban-cars	cars-classifier	DOTNET|6.0	v6.0
tseries-urban-buildings	buildings-location	v4.0
tseries-urban-weapons	weapons-catalog	DOTNET|6.0	v6.0
targets	targets-catalog	DOTNET|3.1	v4.0

Rows 1 and 3 were updated already, row 2 is not .NET, and the last needs to be updated
