fix: preserve trailing newline in vault-read.sh output

path=$1

# Get the kv sec from path in json

j=$(vault kv get -format=json $path)

j=$(vault kv get -format=json "$path")

return_code=$?

if [ "$return_code" -ne "0" ]; then

f=$(echo "$j" | jq -r '.data.format//.data.data.format' 2> /dev/null)

v=$(echo "$j" | jq -r '.data.value//.data.data.value')

# jq -j adds no trailing newline; the trailing-x sentinel preserves

# any newlines in the value that $(...) would otherwise strip.

v=$(echo "$j" | jq -j '.data.value//.data.data.value'; printf x)

v=${v%x}

# if value format is base64, decode it

if [ "base64" == "$f" ]

    echo -n "$v" | base64 --decode

    printf '%s' "$v" | base64 --decode

else

    echo -n "$v"
