I was in the middle of transferring a file over a slow link (768k) using 'scp'. The system on this end got rebooted by an overzealous co-worker... I've got 500+ megs of the file here and 725 megs to go. I'd really hate to start over. I fear that the answer to my question is that I will have to start over. But I was wondering if anyone here knows if there is a way to continue a failed file transfer.

Unless the file transfer software that you are using supports continuation of interrupted transfers, there is really no way that you can continue from where you were cut off.

Just one thing... never tried it.. if it is a large text file, you could check how many lines have been transferred to the remote end and send across the remaining lines using tail. But if it is an archive/binary/something similar, there is no hope.

You could try using the split command. On the source system, do:

$ split -b [bytes of xfered file] [filename]

You'll get two files. scp the second one over and then, hmm, try cat'ing them together into a single file.

You should try it with a much smaller file first to make sure it works for you of course. I tried it with a small compressed file and it worked for me Sun to Linux.

split a small util into two, scp each part over and then cat them into the util again.

Oh well... I wound up just retrying and grabbing the whole file overnight. The 'split' suggestion sounds interesting enough to experiment with. Thanks.
