how to get stderr
Hello

I try to store stderr into a variable, then if this var is not empty i send an email and stop my script.

I think my problem is due of "<$dump" into my command line.

Code:
my bad command line (see samples below on this post)
if ! $returnedStr ; 
 then
     echo ERROR READING DUMP:  $returnedStr
  exit 1
 else
  echo cool ($returnedStr)
 fi

allways returns "cool" even if "my bad command line" throw an error.

Here all syntaxes i tested for "my bad command line":
Code:
exec 2>&1
returnedStr= `mysql -u theuser --password=thepassword < dump.sql`

Code:
returnedStr= `mysql -u theuser --password=thepassword < dump.sql 2>$1`

Code:
mysql -u theuser --password=thepassword < dump.sql 2>>$returnedStr

May someone give me the tips please?

NAME

       script-email - Amanda script to send email notifications

DESCRIPTION

       script-email is an Amanda script implementing the Script API. It should not be run by users directly. It sends a notification email to the
       addresses specified in the MAILTO property.

PROPERTIES

       This section lists the properties that control script-email's functionality. See amanda-scripts(7) for information on the Script API,
       script configuration.

       MAILTO

	   List of email addresses that will receive an email on command execution. It is a multi-valued property:
	     property "MAILTO" "amanda@domain.com" "sysadmin@domain.com" "amandauser@domain.com"

EXAMPLE

       In this example, script-email is scheduled to be run before the DLE, on the server.  The unqualified email address amanda will be passed to
       the email system unchanged.  The script is then attached to a dumptype, which can then be specified for any DLEs which require
       notification.
	define script-tool pre-email {
	  comment "email me before this DLE is backed up"
	  plugin  "script-email"
	  execute-on pre-dle-backup
	  execute-where server
	  property "mailto" "amanda"
	}

	define dumptype user-tar-email {
	  user-tar
	  script "pre-email"
	}
