Questions tagged [command-line-arguments]

Programming command line utilities that take parameters.

This tag should have questions relating to programming command-line utilities that take arguments.

A command line argument is a parameter passed to a command line program. For instance git status is the Git command line program with the parameter status. Git then acts accordingly to that parameter.

Command line arguments are used in command line programs from the Command Prompt on Windows, a shell on Unix and the Terminal program on Mac OS. These are not visual GUI programs, they are text based.
