robo: Run a specific command.
$ robo ${foo}
try on your machine
The command robo ${foo} is using the robo command and passing it a variable named foo as an argument.
${foo} is a variable placeholder, typically used in scripting or programming languages, where foo is the name of the variable. The ${} syntax is used to access the value of the variable and substitute it into the command.
So, when the command is executed, the value stored in the variable foo will be inserted into the command in place of ${foo}. For example, if foo is assigned the value "bar", the command would be executed as robo bar.
