fork and exec ftp
Hi,

I need to find/implement an application that FTPs (puts) all new files in a certain directory to an external storage unit. This application should check for new files every 10 seconds (leaving the FTP connection open in between the 10 seconds).

The easiest way would be if there are programs that I can use on solaris to accomplish this (I know some on Windows, but none on solaris).

Or maybe it can be done with scripts ? (I have no experience with that)

Or I could (in C++) fork and exec (solaris ftp) and use 2 pipes to communicate between my parent process and the ftp. But I'm not sure if it's possible to catch the output of the solaris ftp in a pipe, so that I can use it in my parent process. Until now I've only used uni-directional communication between parent and child process.

I hope to get some ideas on what you think is the best way to do this.
Thanks.

install-solaris

install-solaris(1M)													       install-solaris(1M)

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.
