Introduction=========== /share2 is a backup of /share (each has many subdirectories)
cp -u /share/* /share2 operates as described with man docs. The cp -u command only copies over newer files or when no file exists within /share2 Issue===== The intent is to only update newer files within each sub-directory of /share and /share2. But ... by trying to do a recursive descent with cp -ru /share /share2 I am prompted to "confirm" overwrite for every source file that is newer than the target file? Is it normal behaviour? Does using the -r option negate the -u option? I am trying to do limited backup copies from /share to /share2 and only want to copy newer or missing files /dirs. I tried with rsync with the checksum option. Execution to do the cp -ru equivalent takes excessive amounts of time. Should the -r negate the -u function option? Regards Leslie Leslie Satenstein
