#!/bin/sh

get_json_response(){
  status=$1
  mode=$2
  errorcode=$3
  json_response=`python getJsonResponse.py $status $mode $errorcode`
  return json_response
}

get_json_response 0 0 0 

I get the following error when I try to run the above code -

./tryfunction.sh

./tryfunction.sh: line 8: return: json_response: numeric argument required

How should I rectify this error?

I need to redirect the output of a command that I am running to a log file with timestamp (hence a function instead of the log file itself) but the error and the output, both should not be showing in the console. The following -

command | my_func 2> /dev/null 

is not working.

Something like

command 2> logfile

works, but I can't record the timestamp in the second case. What should I do?
