UNIX for Dummies Questions & Answers

Hi,
I ran rsync command to copy all files, directories and subdirectories from /home/dir1 to another Target directory /home/dir2

Now I want to make sure everything is copied over without missing anything. Is there a command I can run which will compare both directories and check to see if I am not missing anything?

Thanks

Try (ksh93, bash):

Code:

diff <(find DIR1 | sed 's|^DIR1/||') <(find DIR2 | sed 's|^DIR2/||')

But just

Code:

diff -r -N DIR1 DIR2

should work too.

Maybe you need replace command md5sum to md5, depend on your system.

With below command, you can find out any files different between two folders, not only the file name.

Code:

find /home/dir1 -type f -exec md5sum {} \;  |sort >dir1.md5.list
find /home/dir2 -type f -exec md5sum {} \;  |sort >dir2.md5.list

diff dir1.md5.list dir2.md5.list

Thank you everyone for all the commands.

if running as a script the exit code from the rsync should be enough to check, and you should always record it or at least check it.

The diff will tell you if the sync wasn't successful, but not why. If you do see that there are differences it's hard to find out why without the exit code. rsync has a lot of exit codes and will highlight errors like file I/O error, received and interrupt etc...

Use rsync a lot, and this has come in useful on a few occassions
