I have a Bourne Shell script that has several functions in it, and allows to be called in the following way:
my.sh <func_name> <param1> <param2>
Inside func_name() will be called with param1 and param2.
I want to create a "help" function that would just list all available functions, even without parameters.
The question: how do I get a list of all function names in a script from inside the script?
I'd like to avoid having to parse it and look for function patterns. Too easy to get wrong.
Thanks, Alex
update: the code. Wanted my help() function be like main() - a function added to the code is added to the help automatically.
#!/bin/sh
# must work with "set -e"
foo ()
{
echo foo: -$1-$2-$3-
return 0
}
# only runs if there are parameters
# exits
main ()
{
local cmd="$1"
shift
local rc=0
$cmd "$@" || rc=$?
exit $rc
}
if [[ "$*" ]]
then
main "$@"
die "how did we get here?"
fi
