RE: [Ssh-sftp-perl-users] RE: (Urgent) Information required on Net::SSH::W32Perl package

[Rishi K. M <kau...@in...>]

Hi Mark,

  Thanks for the reply. Can you tell me why I am unable
  capture the output of "ls -al" in $out. Also after executing
  ssh->cmd, the code is stucking and the control is not going
  to the next statement following $ssh->cmd. Can you explain
  what I need to do for the script to contrinue executing
  all the instructions.

Regards,
Rishi

I think what you are asking is how to trap errors and handle them without
the script terminating? I had the same problem with Net::SFTP which uses the
SSH module. My solution is described in a previous posting which can be
found in the archive.

You can process the @warnings array and take actions based on errors you
recognize. Retry and write failures to a log, etc.
