Hi,
I'm trying to write a shell script that do ftp and download file periodically, this script should be called by a daemon running in the background.

the shell script "script.sh" is as follows:

and the "commands" files is

if I run script.sh it will work just fine.
But when the daemon software calls the "script.sh", the script will send ftp login request to the ftp server, but will not even answer the username or anything.

I believe it is something about child process redirection, but I don't know how to deal with it.

This problem is not only with yafc, it is the same with any ftp client or any application like telnet and so.

can you help?
Thanks !

Do you mean putting it in the background like this:

Exactly
However, I've rewrote the daemon program, previously the stdin stdout stderr where closed.
Now I just opened them and now it works fine, except that it outputs text that I don't want.
So I need to test how it will work when all telnet sessions disconnect.

Thank all for responses.
But let me know if I'm doing something wrong
Imo post the daemon code when I get to my pc.

I've checked the daemon software, before the script call, I've closed all the std I/O.
after openning the stdin stdout stderr in the daemon, it worked fine.

Thanks for the ideas !
