lua:tldr:77219

This command is invoking the Lua interpreter and executing a Lua script directly from the command line. Here's a breakdown of the command:

• lua: This is the command to run the Lua interpreter.
• -e: This option allows you to directly execute Lua code provided as a string argument instead of running a script from a file.
• '${print("Hello World")}': This is the Lua code that will be executed. It is enclosed in single quotes to prevent the shell from trying to interpret any special characters within it. In this case, the Lua code is print("Hello World"), which will output the string "Hello World" to the standard output.

So, when you run the command lua -e '${print("Hello World")}', it will execute the Lua code print("Hello World"), resulting in the output "Hello World" being displayed in the console.
