Thanks to

Torsten Metzner

He is the only person to answer my question. I am so glad he was able to
help me. He sent me several examples of how to set up what I needed done
and he really came through!

Basically, what my problem was is that I did not have the commands in the
right script files. The examples that I was sent by Mr. Metzner pointed
that right out. What I was doing was scheduling a null job and then calling
the ftp. I am glad to say now that it works the way I wanted.

Hope this helps somebody else out there!

 -----------The ONLY response that I received from Mr.
Hello Gonzo,
have a look at the following example. On my machine it works without
a problem.

130: tom@galois[~/tmp]> more muff

ftp << EOF
cd doc
cd books
cd X-und-Motif

131: tom@galois[~/tmp]> at -s -f muff now + 2 minutes
warning: commands will be executed using /bin/sh
job 829652280.a at Tue Apr 16 12:58:00 1996
132: tom@galois[~/tmp]> at -l

133: tom@galois[~/tmp]> uname -a
SunOS galois 5.4 Generic_101945-32 sun4m sparc

So what are your problems ? Do you have a problem with this example on
your machine or does it works well ?

|What I am trying to do is to set up a script file that I can pass
|to telling it the site to ftp to and the time to do it.

OK here is a skeleton for your problem.

175: tom@galois[~/tmp]> more muff2

# Here should be some code for testing the arguments

# Here it is assumed that $1 == ftp-site, $2 == date in at format

# Solution without a script file

at -s "$2" << EOF
ftp $1 << EOF2
cd doc
cd books
get .dirinfo

# Solution with a script file. E.g. you can generate the script file
# within this script too. You can use $1 in this step

# It's assumed that the file muff exist.

at -s -f ./muff "$2"

176: tom@galois[~/tmp]> ./muff2 "now +2 minutes"

Ah, yes my .netrc file looks like:

186: tom@galois[~]> more .netrc
login ftp
187: tom@galois[~]> ls -al .netrc
 -rw------- 1 tom mupas 69 Apr 16 12:39 .netrc
188: tom@galois[~]>

Hope this helps,
