Verbose mode

This article is about computing and user interface design. For speech or writing that uses more words than necessary, see Verbosity.

In computing, Verbose mode is an option available in many computer operating systems and programming languages that provides additional details as to what the computer is doing and what drivers and software it is loading during startup. Used as a flag in a computer program, it produces detailed output for diagnostic purposes thus making it easier to debug.

When running programs in the command line, verbose output is typically outputted in standard output or standard error.

Many command line programs, such as cURL^[1] or Bash,^[2] can be set to verbose mode by using a flag, such as -v or --verbose.
