[Expectperl-discuss] Some issues I am getting , please solve that

[praveen m. <mal...@gm...>]

Hi Guys,

I have problem with executing the remote command , like mkdir , chmod
etc... . If they are executed successfully they doesn't return
anything. I need someway to verify that they got executed
successfully.
Is there any idea?

Second problem I have is that I am executing the remote command ,
first I make the ssh connection then I send the command one by one.
Problem is that when will I get to particular command is get finished.
because I guess slave system is not returning the EOF as that is
closing the stdout may be stdin also. I did something like that...

$exp->("commad;echo command finished");

and I expect the  "command finished". $exp->expect("600","command
finished"); Here I am hardcoding the 600 seconds to wait for that. If
any script/command takes more than 600 seconds then obiviously
it will fail. I want to wait for forever until I get the "command
finished". Please don't tell me to do the $exp->expect(undef) because
I am not able to receive the EOF from slave system. I do not want to
put any
time limitation like 600 seconds. I want it should wait for forever
for "command finished" not for EOF.

I read all the tutorial  what I get is:
ou are probably on one of the systems where the master doesn't get an
EOF when the slave closes stdin/out/err.
One possible solution is when you spawn a process, follow it with a
unique string that would indicate the process is finished.
$process = Expect->spawn('telnet somehost; echo ____END____');

And then $process->expect($timeout,'____END____','other','patterns');

I did not get this line what the 'other' and 'pattern' mean over here.

If anyone is able to solve this problem really that will be better for me.

Thanks,
