RE: [Expectperl-discuss] trapping remote shell stderr

Why not do 2>&1? Redirect stderr to stdout?

Subject: [Expectperl-discuss] trapping remote shell stderr

 

Hello perl expect list,

 

Please forgive is this is totally obvious, but I've been searching books
and on-line searches way too long!

 

Here's my problem.  I spawn a ssh session to a remote box, and run a
command.  If the command is successful, I just get a new prompt, but if
it fails, the program spits out an error on STDERR.  Currently,
$exp_object->exp_before(),$exp_object->match(), and my
$exp_object->exp_after() objects contain all the STDOUT info, but no
STDERR info.  How does one trap the STDERR strings?

 

On a side note, is there a simple way to get the bash return code from a
command sent to a spawned ssh shell?  Right now I'm doing a "echo $?"
and expecting "\d\r" and parsing the string in $exp_object->match();

 

Thanks!!
