Using rsync with -u option
Lets continue with your RHCE Training topic.
Consider a typical sync situation in a company.
You are doing sync of your local file to a remote server using rsync command. Now if a file is modified at the remote server, which you don’t know and for good reasons you never (or might not) wants to overwrite the new modified file with the old file at your end.
