PERL expect o/p

AlbertJJ · 03-25-2011, 11:35 PM

Hello geeks,

Could you please tell me how to get output of last command executed through expect(in PERL) so that i could analyse and process it for the next steps? What if the last command output if long?(multiline and multicolumn). Is it possible to redirect the o/p to a file and then process it?

Thanks.

Ok. The Problem is:

I want to get the warning messages when a command is executed and take action based on the warning messages.

prompt>delete fs
WARNING: Are you sure(Y/N).. backup is running.

In the above scenario I need to get the WARNING message as input before proceeding and then send a 'Y'.
The waning may not be displayed as shown below:
In some cases if backup is not running:

prompt>delete fs
Done...
