 # Nathan's Backup function.
 # It's best to create backup files by moving the original file aside to its new name with mv and the ncopying it back to its original name.
 # cp -p preserves original file's set attributes.
 # mv and cp -p preserve the original file's settings like the time it was created and modified.
 # Also, be advised, processes might have an open reference to the original file. This process will not cause them errors. Be aware of this, if you are expecting errors from those files.
 # This defines a backup bash function bakmvcp that timestamps a new file name and does the switch for you.
function bakmvcp () {
    newname=$1.`date +%Y%m%d.%H%M.bak`;
    mv $1 $newname;
    echo "Backed up $1 to $newname.";
    cp -p $newname $1;
