I'd like to list the currently defined functions in dash. Is there any way of doing that?
The closest I've been able to come up with is type which can be used to test if a function exist, but other than that I'm stumped.
P.S. I'm talking about dash here (not bash or zsh).
Looking at exec.c it seems that no, there is none - the table is static, there's no such functionality in the file and none of the exported functions (unsetfunc etc) appear to offer the possibility of iterating, so unless I missed something I'd say you'll need to write a patch :)
