cp -r /tmp/abcd.in /tmp/smith.in

when i used the above command .abcd is not captured as it stayss only for fracion of sec
Thanks,

Is it always the same file name? If so, you might make a hardlink to the file before the process runs. smith.in and abcd.in will really be the same file, but smith.in will continue to exist after abcd.in is deleted.

This will be foiled if your transaction process deletes abcd.in before it overwrites, however.

Code:

$ touch /tmp/abcd.in
$ ln /tmp/abcd.in /tmp/smith.in
$ run_process
# does /tmp/smith.in now have the contents you want?

This could also serve as a classroom example of why temp file names should be properly randomized to prevent these shenanigans.

What is this transaction process? Ideally you could just configure it to keep transaction temp files around instead of making something ugly like this. If that's impossible that's quite unfortunate.
