I have a simple shell script. What i'd like to do, is copy the files in
/home/imp/imp/msgs/bak/, but only if they are newer in the source directory than the destination directory.
cp /home/imp/imp/msgs/*.MIX /home/imp/imp/msgs/bak/
cp /home/imp/imp/msgs/*.BRD /home/imp/imp/msgs/bak/
cp -u, but it doesn't seem to work for me.
