> also, what does a traditional rc function do with a shell block?
invoke it. i did something in a variant of 7th edition shell that was roughly
similar.
i remember! i converted {block} as arguments into shell functions exported to
the environment
(having added 8th edition style shell functions and exported shell functions to
7th edition shell).
the shell replaced the {} block by the function name before calling the command.
thus allowing
find usual-find-syntax -exec {mv $file /n/distant/$file}
where the modified find put the current name in the environment $file, removing
the need for {} and the \;
find saw ... -exec my-exported-fn-name, and execvp would invoke /bin/sh -c
my-exported-fn-name.
time {a | pipe | line}; nohup {another; sequence; of; commands}
this relied on the environment not being shared, of course
and having the source to 7th edition.
