Re: Calling script vs one-liner?

I've already written about this issue many times. incron doesn't work
like a shell interpreter and thus it can't recognize shell syntax
including output redirection and so on. All the parameters given after
the program executable name are treated as program arguments. Therefore
no error is reported. Currently there is the only way how to use those
constructions like output redirection or pipes: to write a script. There
are some requirements for this such as #0000446 for the future versions
of incron but the more complex way described above must be used for now.

Lukas
