bash: is it possible to call a function in a parameter to another function?

[PryGuy]

Good day everyone!
I write a script and would love to do the following thing:

MACADDRESS=(`getVar "toLower "Client MAC""`)
I understand the syntax is not right, but as you see I want to use the function toLower' in a parameter while calling getVar. I could use two lines instead of this one, but I'm sure bash is flexible enough to be able to do it in one line.
Thanks in advance.

try:


MACADDRESS=($(getVar "$(toLower "Client MAC")"))

You have to ask yourself - why did i use the `` operator ?
can i use it more than once?
beren got it right and he uses the $() operator in this case.

so if f1-3 are functions you can always run

var=$(f1$(f2$(f3 "foo")))
