-====An Important Notes====
+====Main rsync command usage summary====
 A trailing slash (/) at the end of the first argument in the rsync command: ''rsync -a dir1/ dir2'', mean “the contents of dir1”. The alternative, without the trailing slash, would place dir1, including the directory, within dir2. This would create a hierarchy that looks like: ~/dir2/dir1/[files]

   *''-a'' is the flag for archive.  Keeps original dates and permissions on copy and also recurses, copied sub-directories and content.
+  *''-u'' only copies source files where they are newer than destination files (based upon file modification dates)
+  *''--delete'' deletes files on the destination where they are not on the source.  **//Use with care!//**
+  *''-n'' is for dry run, no changes are made, but proposed output is seen
+  *''-P'' keeps partially copies files and reports progress
+  *''-h''' human readable file sizes
+  *''-v'' increase output verbosity
+  *''-z'' compress files on transfer, note does not necessarily increase transfer speeds, dependent on file types transferred and CPU speeds
 Always double-check your arguments before executing an rsync command. Rsync provides a method for doing this by passing the ''-n'' or ''%%-–%%dry-run'' options. The -v flag (for verbose) is also necessary to get the appropriate output:
