Multiline shell script should take interpreter from first non-blank line

XMLWordPrintable

      When using a mutli-line quote, the interpreter must be on the first line, which doesn't look as nice.

      Works:

      sh """#!/bin/bash -xel
  set -o pipefail
  # Do stuff.
  """

      Want:

      sh """
  #!/bin/bash -xel
  set -o pipefail
  # Do stuff.
  """

      (The latter will be passed to the default shell and ignored as a comment since it is on the second line.)

          A workaround of putting .trim() at the end of the triple-double quote does work:

          sh """
  #!/bin/bash -xel
  set -o pipefail
  # do stuff
  """.trim()

          Erring on the side of using the supplied input exactly rather than trying to guess what was meant.
