$ fast --single-line
try on your machine
The command "fast --single-line" is likely a command used in a software tool or a programming language called "fast."
The "--single-line" flag or option is used to specify a specific formatting or output style to be applied to the command's execution result.
In this case, it seems that the "fast" tool has an option to display the output in a single line format, rather than a multi-line format. This can be useful in cases where the output needs to be compact and concise. The "fast" tool would execute its functionality or computation, and then the "--single-line" option would format the resulting output in a single line format.
