JSON encode in bash -

is there better alternative doing:

echo "{\"error\": \"must executed using user account 'admin'.\"}" >&2;

in bash scripts?

you try here document:

cat <<eot {"error": "must executed using user account 'admin'."} eot

this works unless have single line containing eot in text wish cat. if that's problem, can select alternate token, e.g.

cat <<foo eot foo

additionally, if find basic here documents resulting in unwanted expansion, e.g.

cat <<eot foo$a eot

will try expand $a, can quote here document token stop expansion:

cat <<'eot' foo$a eot
