banner: Print the text message as a large banner (quotes are optional).
$ banner "${Hello World}"
try on your machine
The command "banner ${Hello World}" is used to create a big ASCII art representation of the text "Hello World".
Here is a breakdown of the command:
- "banner" is the name of the command itself. It is used to create large characters from ordinary ASCII characters.
- "${Hello World}" is the input given to the banner command, enclosed within double quotes (""). The ${Hello World} is a variable placeholder, where the text "Hello World" is the value that will be inserted into the variable.
Note that if you execute this command directly in a Unix-like operating system (e.g., Linux), you might encounter an error. This is because the variable syntax ${...} is used for variable substitution within shell scripts, but it requires a valid variable name without any spaces. So, for the command to work correctly, the text should be without spaces like this: banner "${HelloWorld}".

never run a command you are not sure if it is safe.
