Shell Programming and Scripting

OK... As far as I can tell this script is finished. Here was my testing process.

1) Delete a file from $DST. Rerun script. Did the file copy again from $SRC?
NO = PASS

2) Delete the entire directory structure under $DST. Delete the MD5 list file. Rerun script. Did it recreate the $DST structure from $SRC?
YES = PASS / NOTE: Must retain "photos-new/" folder, but can delete entire structure underneath that.

3) Delete the MD5 list file. Do not delete any files. Rerun script. What happens? Examine debug output.
PASS / Seems to cp and overwrite the files in $DST. This is acceptable.

4) Delete a file from $SRC. Rerun script. It should not copy any files. Did it?
PASS

5) Delete the directory structure under $DST. Delete MD5 list file. Run script as root. Does it work and assign ownership correctly to all child objects?
YES / PASS

6) Copy a file in $SRC to $SRC without changing its contents. Run script. Did the file copy over to $DST?
NO = PASS

7) Modify the file copied in test 6. Run script. Did the file copy over to $DST?
YES = PASS

8) Delete the MD5 list file. Do not delete any files in $SRC or $DST. Modify a file in $DST. Rerun script. What happens? Examine debug output.
PASS / Files that were modified in $DST were overwritten with files from $SRC with same filename if the MD5 list is deleted.

Now, someone told me to mark the thread as solved by using the "Thread Tools" menu, but my Thread Tools menu does not have the option to mark the thread solved. Am I missing something?

I'm glad you were able to get your script working.

About 12 minutes after you posted the first message in this thread, you changed the thread's Title from Making a script to copy files not seen before (using md5sum) to Need to make a script to copy files not seen before (using md5sum). To mark the thread solved, you just need to edit that message again adding [Solved] to the start of the title. (I've done that for your this time; but now you know how to do it next time.)
