Redirect Standard Error to /dev/null is not working.
Hello.

When I run a .ksh that contains the command below, and there is no file available in the source location the "FILE_NAME_*.CSV not found" error is still being displayed.

Code:
FILEN=$(ssh ${SOURCE_SERV} "cd ${SOURCE_LOCATION} ;ls ${FILES}") 2> /dev/null

.

This is interfering with the rest of the script, as it is not exiting as required, and is continuing to the next command (See below).

Code:
echo "- Listing available file(s) on ${SOURCE_SERV}${SOURCE_LOCATION}:\n"
		FILEN=$(ssh ${SOURCE_SERV} "cd ${SOURCE_LOCATION} ;ls ${FILES}") 2> /dev/null
		print ${FILEN}
	if [ $? -eq 0 ]; then
	echo "\n- End of Source of files list."
else
        echo "\t\t#####################################\n\t\t#        NO FILES AVAILABLE.        #\n\t\t#####################################\n\n\n- Exiting script"
	exit 0
fi

Can anyone advise what I am doing wrong with the redirection? Basically If there are no files available, I need to echo the warning and exit the script successfully.

Thanks in advance.

Ignore me,

I have fixed it with the following:

Code:
echo "- Listing available file(s) on ${SOURCE_SERV}${SOURCE_LOCATION}:\n"
		FileExists=`ssh ${SOURCE_SERV} "test -f ${SOURCE_LOCATION}/${FILES} && echo 1 || echo 0"`
	if [ ${FileExists} = 0 ]; then
	echo "\t\t#####################################\n\t\t#        NO FILES AVAILABLE.        #\n\t\t#####################################\n\n\n- Exiting script"
	exit 0
else	
	FILEN=$(ssh ${SOURCE_SERV} "cd ${SOURCE_LOCATION} ;ls ${FILES}")
	print ${FILEN}
	echo "\n- End of Source of files list."

Thanks for looking though!
