Very Computer

I copied a unix executable file from my account to disk drive, and now I want
to copy it back on to my account. (xview) But when I copy the file back to my
account and run it, it gives me a segmentation fault, and a core dump. DOes
know how to do the file transferring without haveing any core dumps and have
the file working?

        Thanks very much!

Firstly, are you sure the executable was working before you downloaded it
onto the disk ?  you may not have compiled it correctly, even thought it
produced the final executable, and that's when you usually find core dumps
and segmentation faults when you run it.

However, if this was a utility installed on the system, which means it was
working properly to start with, then did you make sure when you downloaded
the file, you used BINARY transfer mode?  (i.e type --> bin at the ftp
prompt) .  Also, did you also uploaded it back using BINARY transfer
mode?  (use ASCII for text files only)  

If you did transfer the file using the correct mode, then i don't see
how FTPing the file back and forth could possiblly damage the file, and
causing core dumps.

Hope this helps,

BEFORE you do the transfer.  (I stands for Image, and means that ftp won't do
any conversion on the file as it transfers it.)

This applies (usually) to _all_ stages of the process, so if (like me) you have
to use multiple steps, _all_ of them should use a binary transfer.
