Is there a way to simulate/preview (but not really do) rsync ?

As a first step in developing a rsync procedure I would like just to simulate the
coded rsync command. In other words I want to preview the transferred files at first.

How can I do such a simulated run?

RTFM...

man rsync
/dry-run <Enter>

Which part of the manual page describing the "-n" (or "--dry-run") option
do you not understand?

rsync -n
man rsync

try the '--dry-run' or '-n' options to the rsync command

Have a look at the rsync man page, there's an option -n.

Did you read man rsync? From the description, the -n option seems to do what
you want.

From 'man rsync':

-n, --dry-run
This makes rsync perform a trial run that doesn't make any
changes (and produces mostly the same output as a real run).
It is most commonly used in combination with the -v, --verbose
and/or -i, --itemize-changes options to see what an rsync com-
mand is going to do before one actually runs it.

The output of --itemize-changes is supposed to be exactly the
same on a dry run and a subsequent real run (barring inten-
tional trickery and system call failures); if it isn't, that's
a bug. Other output is the same to the extent practical, but
may differ in some areas. Notably, a dry run does not send the
actual data for file transfers, so --progress has no effect,
the 'bytes sent', 'bytes received', 'literal data', and
'matched data' statistics are too small, and the 'speedup'
value is equivalent to a run where no file transfers are
needed.

You chould use 'rsync -v --dry-run [arguments]' I use this to pre-test all
sorts of things.
