Passing variable from bash to perl script
Hi All,
I need to pass a variable from bash script to perl script and in the perl script i am using those variables in the sql query but its giving
error :
Code:
Use of uninitialized value $ENV{"COUNTRYCD"} in concatenation (.) or string at /GIS_ROOT/custom/tables/DBread_vendor.pl line 50.

Can you please help me on thsi as i am new to perl script and tried some options from google but its not working.
bash script logic:

Code:
echo -n "Enter the Country Code - "
read COUNTRYCD
 
echo -n "Enter Start date in YYYY-MM-DD format - "
read STARTDATE[/FONT][/SIZE]
echo -n "Enter End date in YYYY-MM-DD format - "
read ENDDATE
 
echo -n "Enter the Vendor Number-"
read VENDNUM
 
export STARTDATE
export ENDDATE
export VENDNUM

Perl script logic :
Code:
my $DRSQL = "SELECT dest_batch_name FROM Document WHERE dest_batch_name LIKE '$ENV{'COUNTRYCD'}' AND LEFT(entity_ref_id,6) = '$ENV{'VENDNUM'}'[
AND (batch_create_ts BETWEEN '$ENV{'STARTDATE'}' AND '$ENV{'ENDDATE'}')";

ipc::run::debug

IPC::Run::Debug(3)					User Contributed Perl Documentation					IPC::Run::Debug(3)

NAME

       IPC::Run::Debug - debugging routines for IPC::Run

SYNOPSIS

	  ##
	  ## Environment variable usage
	  ##
	  ## To force debugging off and shave a bit of CPU and memory
	  ## by compile-time optimizing away all debugging code in IPC::Run
	  ## (debug => ...) options to IPC::Run will be ignored.
	  export IPCRUNDEBUG=none

	  ## To force debugging on (levels are from 0..10)
	  export IPCRUNDEBUG=basic

	  ## Leave unset or set to "" to compile in debugging support and
	  ## allow runtime control of it using the debug option.

DESCRIPTION

       Controls IPC::Run debugging.  Debugging levels are now set by using words, but the numbers shown are still supported for backwards
       compatibility:

	  0  none	  disabled (special, see below)
	  1  basic	  what's running
	  2  data	  what's being sent/recieved
	  3  details	  what's going on in more detail
	  4  gory	  way too much detail for most uses
	  10 all	  use this when submitting bug reports
	     noopts	  optimizations forbidden due to inherited STDIN

       The "none" level is special when the environment variable IPCRUNDEBUG is set to this the first time IPC::Run::Debug is loaded: it prevents
       the debugging code from being compiled in to the remaining IPC::Run modules, saving a bit of cpu.

       To do this in a script, here's a way that allows it to be overridden:

	  BEGIN {
	     unless ( defined $ENV{IPCRUNDEBUG} ) {
		eval 'local $ENV{IPCRUNDEBUG} = "none"; require IPC::Run::Debug"'
		   or die $@;
	     }
	  }

       This should force IPC::Run to not be debuggable unless somebody sets the IPCRUNDEBUG flag; modify this formula to grep @ARGV if need be:

	  BEGIN {
	     unless ( grep /^--debug/, @ARGV ) {
		eval 'local $ENV{IPCRUNDEBUG} = "none"; require IPC::Run::Debug"'
		or die $@;
	  }

       Both of those are untested.
