Related command
az <command> -o tsv

Description
Windows text-mode output was translating TSV row terminators to CRLF, which leaked \r into POSIX shell command substitution and broke common for x in $(az ... -o tsv) patterns. This change keeps TSV output LF-delimited so row-oriented shell usage is stable on Windows.

  • Output path

    • Override AzOutputProducer.out() for TSV only.
    • Write encoded bytes to the stream buffer when available, bypassing Windows newline translation.
    • Leave JSON/YAML/table and other output paths unchanged.
  • Regression coverage

    • Add a focused test that simulates a CRLF-translating text stream and verifies TSV output remains \n-terminated.
    • Add a guard test confirming non-TSV output still uses the normal text-stream behavior.
for topic in $(az servicebus topic list --resource-group "$RG" --namespace-name "$NS" --query "[].name" -o tsv); do
  az servicebus topic subscription list --resource-group "$RG" --namespace-name "$NS" --topic-name "$topic" --query "length(@)" -o tsv
done

Testing Guide
Use any command that returns multiple rows in TSV format.

az servicebus topic list --resource-group "$RG" --namespace-name "$NS" --query "[].name" -o tsv

On Windows, each row should be LF-delimited so the output is safe to consume from POSIX shell command substitution:

for x in $(az ... -o tsv); do
  printf '%s\n' "$x"
done
