Re: Handling errors when working with files

Using 'open' I cannot say if the 'del' command was done correctly

I believe you're talking about a piped open() to an external command.
The return value from the piped open indicates merely whether the open
itself was successful. The result of the command's execution isn't
available when open returns, because the command has just then been
started, and it may not be done running for some time. Once you're
done running the command, the return value from close() tells you
whether it exited successfully.

Having said that, is the command you're running doing nothing more
important than deleting files and directories? In most cases, you can
do that more quickly, easily, and safely directly from within Perl.
See the unlink and rmdir functions in perlfunc.

Hope this helps!
