Question Error in script
While installing kubernetes, I have to run 1 script. Below is a part of that code. I am getting an error as
Code:
-bash: syntax error near unexpected token `}'

Please help me to find what changes are required for the below mentioned piece of code.


Code:
kube::util::godep_restored() {
  local -r godeps_json=${1:-Godeps/Godeps.json}
  local -r gopath=${2:-${GOPATH%:*}}
  if ! which jq &>/dev/null; then
    echo "jq not found. Please install." 1>&2
    return 1
  fi
  local root
  local old_rev=""
  while read path rev 
do
    rev=$(echo "${rev}" | sed "s/['\"]//g") # remove quotes which are around revs sometimes

    if [[ "${rev}" == "${old_rev}" ]] && [[ "${path}" == "${root}"* ]]; then
      # avoid checking the same git/hg root again
      continue
    fi

    root="${path}"
    while [ "${root}" != "." -a ! -d "${gopath}/src/${root}/.git" -a ! -d "${gopath}/src/${root}/.hg" ] 
	do
      root=$(dirname "${root}")
    done
    if [ "${root}" == "." ]; then
      echo "No checkout of ${path} found in GOPATH \"${gopath}\"." 1>&2
      return 1
    fi
    local head
    if [ -d "${gopath}/src/${root}/.git" ]; then
      head="$(cd "${gopath}/src/${root}" && git rev-parse HEAD)"
    else
      head="$(cd "${gopath}/src/${root}" && hg parent --template '{node}')"
    fi
    if [ "${head}" != "${rev}" ]; then
      echo "Unexpected HEAD '${head}' at ${gopath}/src/${root}, expected '${rev}'." 1>&2
      return 1
    fi
    old_rev="${rev}"
  done<(jq '.Deps|.[]|.ImportPath + " " + .Rev' -r < "${godeps_json}")
  return 0
}

I tried with the suggested option, but it's still not working. I am getting below error :
Code:
syntax error near unexpected token `<'

Code snippet :
Code:
{
  local -r godeps_json=${1:-Godeps/Godeps.json}
  local -r gopath=${2:-${GOPATH%:*}}
  if ! which jq &>/dev/null; then
    echo "jq not found. Please install." 1>&2
    return 1
  fi
  local root
  local old_rev=""
  while read path rev 
do
    rev=$(echo "${rev}" | sed "s/['\"]//g") # remove quotes which are around revs sometimes

    if [[ "${rev}" == "${old_rev}" ]] && [[ "${path}" == "${root}"* ]]; then
      # avoid checking the same git/hg root again
      continue
    fi

    root="${path}"
    while [ "${root}" != "." -a ! -d "${gopath}/src/${root}/.git" -a ! -d "${gopath}/src/${root}/.hg" ] 
do
      root=$(dirname "${root}")
    done
    if [ "${root}" == "." ]; then
      echo "No checkout of ${path} found in GOPATH \"${gopath}\"." 1>&2
      return 1
    fi
    local head
    if [ -d "${gopath}/src/${root}/.git" ]; then
      head="$(cd "${gopath}/src/${root}" && git rev-parse HEAD)"
    else
      head="$(cd "${gopath}/src/${root}" && hg parent --template '{node}')"
    fi
    if [ "${head}" != "${rev}" ]; then
      echo "Unexpected HEAD '${head}' at ${gopath}/src/${root}, expected '${rev}'." 1>&2
      return 1
    fi
    old_rev="${rev}"
  done < <(jq '.Deps|.[]|.ImportPath + " " + .Rev' -r < "${godeps_json}")
  return 0
}

What's your shell version? "process substitution" works only in recent shells.

Code:
$ echo $BASH_VERSION
4.4.12(3)-release

I am running this script through CYGWIN as I could not find any other option to run shell script in windows machine. Please let me know if I need to download the latest version or any other tool to run this script.

What does your bash's man page say about "process substitution"?
