How to check for a sucecssful FTP file transfer???

Hi everybody,

I have a shell script that calls FTP to transfer a file from one
server to another server. Depending upon whether the file has been
ftped successfully or not the script executes the next step. I am
using "$? = 0" to check fo the file transfer status but the FTP always
returns $?=0.
How do I check for successful completion of a file transfer in FTP?
Please give me the specific command,

Thanks,
Sandy.

Grep the output of the ftp command, or have a second file containing the
md5sum of the file to be transferred.

outside the FTP program, you -don't-.

You need a -smart- program that understands the FTP protool, _and_ an
indicate success/failure back to the invoking environment.
*OR* do everything inside the scripting language of a program that knows
how to do FTP transfers.

"KERMIT" is good for the latter approach to your problem.

lastly, you -might- be able to use 'expect' to driver the FTP program,
rather than a here-document in your script. With eough effort you can
probably get 'expect' to figure out when a transfer failed. (easiest to
*assume* it failed, and treat the 'transfer completed' message as the
special condition that must be handled differently.

All these suggestions can work, but they take a lot of effort
to reinvent poorly what UUCP has done well for many years now.

Which:
(a) assumes uucp and all the required 'friends' are available on both
the source ad destination systems.
(b) assumes the OP has the appropriate administrative-level access to do
the required configuration on both systems to make it work.
(c) assumes the OP has the skills/time/inclination to wade through, create,
and test all the arcane onfiguration files require to make it work.

AND ignores far simpler alternatives for small-scale work, such as:
1) rcp
2) scp
3) rsync

Of course, all of those approaches have the same failing as the uucp
approach -- they _fail_to_meet_ the stated criteria of detecting the
successful/failed completion of an _FTP_TRANSFER_.
