[ControlTier] cannot get resource attributes

[Raymond Meng]

I wanna get the value of &{resource.package-install-root} and I tried below command, but got error：-bash: ${resource.properties.install-root}: bad substitution.
ctl -p demo_coreDev -t file -r createUniq.py -c Get-Properties -- -destfile ${resource.properties.install-root}

I also tried replacing ${resource.properties.install-root} with ${resource.package-install-root}, same error occurred.

is there anyone can help me?

First make sure the property you want actually is there (run the Properties command with "-- -format plain" to get a list), then escape the $ sign using a backslash-- \${propertyname}.

It should be said that this is not guaranteed to work, because it requires that the command itself do a substitution. Not all commands do such a substitution. But the escaping would at least get you to the next level of debugging.

thanks Moses Lei.

Though Get-Properties doesn't work, I can get what I want with a python script parsing the output of Properties command with "-- -format plain".
