# Argc [Argc](https://github.com/sigoden/argc/) is a Bash command line framework that utilizes a special comment-driven syntax to provide a command runner and argument parser. Here is a simple Argcfile.sh: ```bash # @describe Example Argcfile # Arguments, options, and flags listed here apply to the main command and all # subcommands. # # For more information about argc, see https://github.com/sigoden/argc # @option --name Name to greet # @flag -F --foo Flag param # @option --bar Option param # @option --baz* Option param (multi-occurs) # @arg val* Positional param main() { echo foo: $argc_foo echo bar: $argc_bar echo baz: ${argc_baz[@]} echo val: ${argc_val[@]} } if ! command -v argc >/dev/null; then echo "This command requires argc. Install from https://github.com/sigoden/argc" >&2 exit 100 fi eval "$(argc --argc-eval "$0" "$@")" ``` Run the script with some sample arguments: ```bash ./example.sh -F --bar=xyz --baz a --baz b v1 v2 ``` Argc parses these arguments and creates variables prefixed with argc_: ``` foo: 1 bar: xyz baz: a b val: v1 v2 ``` You can also run ./example.sh --help to see the automatically generated help information for your CLI. ## Bash idioms Prefer using Bash idioms when working with argc. For example, shellcheck isn't aware of the argc_foo variables, so prefer using `${argc_foo:?}` for required values and values where argc is known to provide the default. For others, use `${argc_foo:-default}`, as appropriate
