[9fans] rc script question

[Steve Simon]

Hi,

rc is not working how I expect it to.

This works fine
echo a b c | rc -c 'a=`{read}; echo @ $a(2-) @'
@ b c @

This i did not expect
echo a b c | rc -c 'echo @ $(2-) @'
@ @

Perhaps I need some expectation managment?

i assumed you wanted a b c as command line arguments in the second case,
not echoed in.
in the first case, you indexed a variable. in the second case, you indexed
nothing.

% rc -c 'echo @ $*(2-) @' a b c
@ b c @

@ @

rc -c 'shift; echo @ $* @' `{echo a b c}

surprisingly, * can be assigned to.

echo a b c | rc -c '*=`{read}; shift; echo @ $* @'
echo a b c | rc -c '*=`{read}; echo @ $*(2-) @'

and this is why there's no bourne's "set" builtin.
