$ ./run hello-world
Hello Worldwhere hello-world is a function defined inside run e.g.
run_hello_world() {
echo "Hello World"
}Note that run will match at runtime underscores or dashes, you can use either.
Create a new function inside run with the prefix run_ then call the function on the command line without the run_ prefix.
Functions can of course be composed inside the script, and you can write functions in other files and include them in run via source e.g.
extras.sh
run_extra_script() {
echo "show me what you got"
}run:
...
source extras.sh
run_hello_world() {
...$ ./run extra-script
show me what you got
