Take the 2-minute tour ×  The scenario is this: Machine A has
files I want to copy to Machine C. Machine A can't access C
directly, but can access Machine B that can access Machine C. I
am using scp to copy from Machine A to B, and then from B to C.
Machine B has limited storage space, so as files come in, I need
to copy them to C and delete them from B. The second copy is
much faster, so this is no problem with bandwidth.  I could do
this by hand, but I am lazy. What I would like is to run a
script on B or C that will copy each file to C as each one
finishes. The scp job is running from A.  So what I need is a
way to ask (preferably from a bash script) if file X.avi is
"done" copying. Each of these files is a different size, and I
can't really predict size or time of completion.  Edit: by the
way, the file transfer times are something about 1 hour from A
to B and about 10 minutes from B to C, if time scale matters at
all.  share|improve this question  6 Answers 6  up vote 3 down
