$ print ${filename}
try on your machine
The command "print ${filename}" is used to display the value of the variable "filename" in computer programming languages or scripting languages like Python, Perl, or Bash. The syntax "$" signifies that "filename" is a variable, and when it is enclosed within curly braces "{}", it provides better readability and helps separate the variable name from the surrounding text. So, when this command is executed, it will print or display the value stored inside the variable "filename" on the output screen or console.
