Question

Is it possible to use CRON to upload a file via FTP? If yes how can I call FTP to run an upload?

Answer 1

Assuming a UNIX-like operating system you could setup a cron job that pointed to a shell script like the following:

#!/bin/sh
cd [source directory]
ftp -n [destination host]<<END
user [user] [password]
put [source file]
quit
END

Depending on your ftp client defaults and the source file type you may need to specify binary prior to the put.
