Hello and thank you for reading this.
I have consulted several resources about the cp command, such as: http://www.computerhope.com/unix/ucp.htm. I still can't find my answer.
What I would like to do is to move files from one folder to another, replacing the existing contents ONLY IF the time signatures are identical. Otherwise I would like to move the file but to keep both copies (name.file and name.file(2) ..or something equivalent). Any suggestions for how I might accomplish this?
