Re^2: system() call mis-directs?

Thank you both!

@sundialsvc4, thank you but logs have been checked and re-checked.

@jcb, you may have nailed it.

$sensors looks like this: ABC-00-DEF-1234 --sitename=Charon .

The double hyphen is suspicious as is the '='

Will test out tomorrow and post results. Thank you !

Your sample does not contain any troublesome characters, but the shell splits on unquoted whitespace, which my earlier suggestion would prevent by wrapping `$sensor` in shell quotes before passing it to the shell. My immediate suspicion is that you may have some "odd" site names. In particular, an ampersand is both reasonable in human-readable names and special to the shell. The best way to fix this would be to get the shell out of the picture and use the list form of system. You will also need to use open or sysopen to rearrange your filehandles so that the second child will inherit `STDOUT` and `STDERR` opened for append on the `worklog` file, while the first child keeps its original `STDOUT` somewhere to report the result from the second child.
