How to concatenate the username in an XML variable?

I'm defining an argument in my ROS launch file, which is an XML file, and I would like to replace user in the definition of the path variable with the username variable, that is $USER.

<arg name = "path" default="/media/user/ssd1/data//" />

I've tried combinations of $USER, ${USER}, @USER with no luck.

Is there any way to do this?

Solution

  • You may use the env substitution arg.

    <arg name="path" default="/media/$(env USER)/ssd1/data/"/>
