Interpolation
String interpolation with the $ operator is allowed in a command object, like this:
file = "file1.txt" cmd = `cat $file` # equivalent to `cat file1.txt` run(cmd) #> prints the contents of file1.txt
This is very similar to the string interpolation with $ in strings (refer to the Strings section in Chapter 2, Variables, Types, and Operations).
