 +<code>
 +# always have vP for verbose and progress
 +rsync --modify-window=5 -vPrltD NORMAL THING
 +# NO LUCK for me like this, but adding this does only check file size
 +
 +rsync --size-only -vaP FROM/ TO/

 +# try this
 +rsync --size-only -vPrltD # OR remove -t

 +==== Find and Copy Files Between Two Dates ====
 +
 +Use **newermt** switch to **find** and copy files that are human readable times / dates from one place to another.
 +
 +<code>
 +find /Volumes/6608 -newermt "2024-11-01 00:00:00" ! -newermt "2024-12-01 00:00:00" -exec cp -a "{}" .  \;

 +=== Files in Order ===
 +
 +Sometimes I have noticed files do not happen in order when doing command line things.  Using **xargs** and **sort** allows us to sort the input files so that the order is correct.
 +
 +<code>
 +ls -v j080_202405* | sort | xargs cat > j080_overnight.jps
