I do not understand well your proposal. Could you give a more detailed suggestion?

from daemonmode.jl.

If a script has the following lines

println(stdout,"normal message")
println(stderr,"error message")

Both of the outputs are sent to sock. In a regular script the output could be separated by using
julia script.jl &2> /dev/null which pipes stderr into /dev/null.

The redirection can be seen for example here:

DaemonMode.jl/src/DaemonMode.jl

Lines 86 to 113 in 24930ea

function serverRun(run, sock, shared, print_stack)
redirect_stdout(sock) do
redirect_stderr(sock) do
try
if shared
run(Main)
else
m = Module()
add_include = Meta.parse("include(arg)=Base.include(@__MODULE__,arg)")
Base.eval(m, add_include)
run(m)
end
println(sock, token_end)
catch e
if print_stack
serverReplyError(sock, e, catch_backtrace())
else
serverReplyError(sock, e)
end
end
end
end
end

I don't need this at the moment and I think the implementation could be tricky, but I guess it could be useful. One way I see would be to encapsulate the two outputs on the sock stream. The other might be to use a second channel.

As a workaround one might use Suppressor.jl inside the script.
