UNIX for Dummies Questions & Answers

I have several servers, A, B, & C that run various routines then scp the results to server X. On X I then have to do some data manipulation with the received files before sending the files on to another location. Because of policy here I cannot pull the files from servers A, B & C, but have to allow them to initiate the transfer.
What I would like to be able to do is, on server X, monitor the receipt of the files from A,B & C via a script and when the transfer is complete kick off the data parsing routines that run on X.
Can someone tell me how to monitor the incoming scp sessions so that I can identify each one and tell when the transfer is complete for each of the servers?

Thanks

One solution is to create a tiny "flag" file that you send last. That way, the receiving server can just wait until that file exists and it will know that the real files have arrived.

I don't know if you can predict the order in which the files would be sent in an scp session, but you can always do a quick second scp session to send the flag file.

It copies the files in the order you give them on the command line, n'est-ce pas? If you use wildcards, I would expect the wildcard expansion to simply expand one token into many, so you can still say

Code:

scp file* and* stuff* .signalfile server:path/on/server
