OK then, Paul.
Please show me how to use 'do script' in the Terminal to download via ftp
the last-named file of a sequentially-named series of files from a specified
directory.
For example, the /pub/files/ directory on the ftp server ftp.mydomain.com
contains a number of files: file01.txt file02.txt and file03.txt as well as
an unspecified number of other files.
I want an AppleScript to use the terminal to login to the server using a
specified username/password and download only the latest filexx.txt file
which right now may be file03.txt, but tomorrow might be file04.txt
I want the script to automatically decide which file to download, although
I'll accept, at a pinch, displaying a list of filexx.txt files for the user
to choose from (although, if you can get that listing the logic to choose
the file is simple).
I maintain this can not be done because you can not retrieve the results of
the previous 'do script' action. You can 'do script "ftp ftp.mydomain.com",
but you cannot interactively log in, or get the directory listing (unless
you want to repeatedly 'get contents of window 1" to read the entire
terminal screen, which may not work with long file listings). You cannot,
therefore see what files are available for download or make the decision as
to which file to download.
You can do this using 'do shell script' (not in a 'tell application
"Terminal" block), because do shell script returns the stdout of the shell
command to AppleScript, and you can react to that. 'do script' in the
Terminal does not.
