\typeout

`\typeout{msg}`

Prints `msg` on the terminal and in the log file. Commands in `msg` that are defined with `\newcommand` or `\renewcommand` are replaced by their definitions before being printed.

LaTeX's usual rules for treating multiple spaces as a single space and ignoring spaces after a command name apply to `msg`. A \<space> command in `msg` causes a single space to be printed.
