Re: Re: Continue Processing Subrouting Until Successfull

Frank,

Thank you for your response. Wouldn't this execute the run sub if $result equals 255? Should I use a until loop instead like:

until ($result == 255) {
  $result = run($_);
}

Also, can you plase explain what this does a little more $result = run($_);

Thanks,
Dru

No, the result is 255 until a success. So you want to continue looping until $result is not 255. As for the $result = run($_); If you notice I added a return() into the run subroutine. This will return the exit code of the ssh() call, which will be 255 ( according to OpenSSH's documentation ) if there is an error or the exit code of the command being run if there isn't an error. If your down.pl script returns a different exit code you'll want to adust your test to not be 255. ----------------------------------- Frank Wiles <frank@wiles.org> http://frank.wiles.org	[reply]

Why use $result at all `while (run($_)==255) { shift @hosts; }` [download]	[reply] [d/l]
