View shell function's current definition

view story

http://unix.stackexchange.com – So I am editing bashrc constantly, and I have a terminal open with a working function definition, although bashrc has been updated with a wrong function definition. (Because the definition do not change until I source the updated bashrc) How can I look up the working function definition in this case? For example, if I type: alias function_name I can see what the definition is for that alias. Is there a command similar for function? If not, is there a command to output entire bashrc that the current terminal is using? (HowTos)
