node.js - Equivalent of <() for sh? -

i have script runs in zsh.

cat foo.txt <(node bar.js) > out.txt

this little script configured in node.js module uses /bin/sh execution. problem sh fails @ <

/bin/sh: -c: line 0: syntax error near unexpected token `('

the goal concatenate contents of foo.txt , output of executed script single out.txt

can somehow achieve same thing using sh?

you can achieve same effect original script grouping commands within {...} this:

{ cat foo.txt; node bar.js; } > out.txt

using <(...) can cat awkward , inefficient. using grouping better , more portable, think it's improvement on original script.

And
