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?

MAILPING-STORE(1)						     Mailping							 MAILPING-STORE(1)

NAME
mailping-store - store email from stdin to a mailping incoming maildir SYNOPSIS
mailping-store DESCRIPTION
mailping-store reads an email from standard input and writes it into a maildir chosen according to following logic: 1. If EXTENSION is not set, select Maildir. 2. If EXTENSION is set, ensure its value is safe to use, and select EXTENSION/incoming. mailping-store is usually run from a .forward file, and thus the filenames above are relative to the home directory of the account in question. Normal use Normally, mailping-store is used to ease the setup of new circuits to probe from mailping-cron. This is done with a system account mailping using <mailping@yourhost.example.com> as the from address, and <mailping+circuitname@yourhost.example.com> (or some remote address aliased to that) as the to address. In fact, these are the default values for from and to, so you can just skip creating those configuration files. This allows adding new test circuits without any changes to the email configuration. FILES
/var/lib/mailping/state/circuit/incoming Maildir to store the email to. /var/lib/mailping/state/Maildir/ Maildir to store the email to, if no extension was given. ENVIRONMENT
MAILPING_STATEDIR Override the location of the state directory. Circuit states are stored in the state subdirectory of this directory, in subdirectories named after the circuit name. Default: /var/lib/mailping EXTENSION Name of the current circuit to store the mail for. SEE ALSO
