Automate FTP login

[Stephen Ng]

I would like to issue one command or write a shell script to excute file transfer using ftp

[suki]

Hi ,
try the following script.


ftp -i -n -v hostname <

[suki]

Hi ,
try the following script.


ftp -i -n -v hostname <

[suki]

Hi ,
try the following script.


ftp -i -n -v hostname <

[Stephen Ng]

Suki,
If I call this script inside another script, could I pass
the filename as a variable thru the first script.
Tks,
Stephen

[suki · Accepted solution]

Yes. U can. Give as an argument to the file.

Example:

filename: ftpscript.sh
--------------------------------
ftp -i -n -v host1 <

[Stephen Ng]

Suki,
I got error when I ran the script.
I've attached two scripts & the result for
you.
Tks,
Stephen

hi,

try this simple one:
#more test.sh
#!/bin/sh
ftp myserver <prompt
cd /home/yd
mput myfile*
bye
EOF


Hope this helps!

No, it didn't work.

Hi Stephen,
Try "m.sh" with this content:

#!/usr/bin/sh
ftp -niv $1 <

A simpler way than trying to pass variables is simply to have a directory set aside for ftp transfers. Then the first script just copies the file(s) into the directory and calls the second script which ftps everything in the directory (mput *.gz) then the first script deletes the files or moves them to an archive directory. This way there is no limit to the number of files that you can pass.

Ron,
That's a good idea. Ijust
have the same thinking.
Tks to all of you.

A much better way to do regardless of whether you set up a dedicated transfer directory is to do with Perl using the Net::FTP module.

The big question to ask yourself is "How do I know that my put(s) or get(s) actually worked and that the entire file(s) was transferred intact?" Chances are you don't know and any of these examples don't know either. That's the beauty of Net::FTP; error checking is very simple.

You can download the NET::FTP module from www.perl.com/CPAN
and installation is trivially easy.

To use this in a script, you would do something like this:

ftp.pl file1 file2 file3
STAT=${?}

if [[ ${STAT} -eq 0 ]]
then
echo "All transfers ok"
fi

This will automatically attempt a re-transmit if a file fails.

ftp has builtin the ability to read a .netrc file (automated ftp). See:

man netrc

for details.
