Hey @zaufi, the --body flag is intended to be a literal string input. If you would like to read from stdin, please use the --body-file argument:

  -F, --body-file file   Read body text from file (use "-" to read from standard input)

So with your example, it would look like:

echo foo | DEBUG=api gh pr comment "$pr_id" --body-file -

With that said, I'll close this out, but let me know if this doesn't work.

Oh, really... My bad (dunno how did I read the help screen %)
