# Command line usage Chloride provides a command line interface for running Argon programs and accessing development tools. ## Running a program An Argon source file can be run by passing its filename to `argon`: ``` argon my_program.ar ``` If the file uses the `.ar` extension, the extension can be omitted: ``` argon my_program ``` Both commands will run the same file: ``` my_program.ar ``` ## Checking the version To display the installed Chloride version, run: ``` argon --version ``` This prints version information for the current installation. ## REPL Chloride also includes an interactive REPL for running Argon code interactively. See the [REPL documentation](repl/README.md) for more information.
