I can define and print the contents of variable called my_var like this:

my_var="hello"
echo $my_var

but if I define:

my_funct {echo "hello";}

how can I recall my function's definition later on?

With the type command:

dennis@lightning:~$ foo() { echo "hi"; }
dennis@lightning:~$ type foo
foo is a function
foo () 
{ 
    echo "hi"
}

Great!, thanks! – Robert Vila Nov 16 '12 at 19:05

To get just the definition without "foo is a function",

$ declare -f foo
foo () 
{ 
    echo "hi"
}
