Hi,

please compare:

sudo ./nosudo -u'#1000' /bin/bash -c "echo -e 'a\nb\nc\n'; echo -e 'a\nb\nc\n'; id -u; id -u;"

with

sudo          -u'#1000' /bin/bash -c "echo -e 'a\nb\nc\n'; echo -e 'a\nb\nc\n'; id -u; id -u;"

Maby requoting can help?

#!/usr/bin/env bash

function requote {
    declare arg
    for arg; do
        arg=$(printf '%q' "$arg")
        printf '%s ' "${arg:-''}"
    done
}

ARGS=$(requote "${@}")
eval "$ARGS"

Usage:
./myscript.sh sudo -u'#1000' /bin/bash -c "echo -e 'a\nb\nc\n'; echo -e 'a\nb\nc\n'; id -u; id -u;"

For now, I've decided to use real sudo instead...

(Also: real sudo can run a command under any uid, while su needs a user with that uid to actually exist. That seems to be a limitation of su, though...)
