pan.sh未在eval中返回返回码

Question

I've got a shell script which is calling Pentaho's pan.sh to execute a job. The job itself is failing, but I can't seem to capture the return code to fail the shell script wrapper.

This is the code I'm using to execute the batch:

echo "Processing $FILE file...";
cmd="./pan.sh -file=$FILE -param:db.name=${DB_NAME} -param:db.host=${DB_HOST} -param:db.port=${DB_PORT} -param:db.user=${DB_USER} db.password=${DB_PASSWORD} -param:dataload.dir=${DATALOAD_DIR}"
eval $cmd
ret_code = $?
echo $ret_code
if [ $ret_code -ne 0 ]
  then
    echo "return code = ${ret_code}"
else
  echo "return code is ok ${ret_code}"
fi;

Then the relevant part of the log that's output looks like this. You can see that it's not outputting anything in ret_code variable. I can't spot what the issue is. It might be bash, or might be pan.sh . I'm not sure.

Answer 1

First, you can't put whitespace around the equal sign in an assignment statement. (Doing so makes it a regular command call, not an assignment.)

ret_code=$?

Second, don't use eval here. Either define a function:

cmd () {
    ./pan.sh -file="$FILE" \
             -param:db.name="${DB_NAME}" \
             -param:db.host="${DB_HOST}" \
             -param:db.port="${DB_PORT}" \
             -param:db.user="${DB_USER}" \
             -param:db.password="${DB_PASSWORD}" \
             -param:dataload.dir="${DATALOAD_DIR}"
}

or separate the command from the arguments:

cmd=./pan.sh
arguments=(-file="$FILE"
           -param:db.name="${DB_NAME}"
           -param:db.host="${DB_HOST}"
           -param:db.port="${DB_PORT}"
           -param:db.user="${DB_USER}"
           -param:db.password="${DB_PASSWORD}"
           -param:dataload.dir="${DATALOAD_DIR}"
)
"$cmd" "${arguments[@]}"
