Hello there,
I'd like to run some shell command and then receive its output *as the
value of some expression*. IOW, I'd like to do this:
(setq output (do-magic "echo Whatever"))
so that `output's value is the string "Whatever".
What should I put in place of do-magic? I skimmed through the manual
section on processes, but I suspect there might be some simple way...
Best,
--
