How can I confirm if azcopy synced successfully a dir? - bash

Question

I have a group of files and directories stored in a container in a storage account in Azure. I am using the sync operation of azcopy to bring only the files and directories that I am missing into a local directory. When executing the command I use the --delete-destination true flag and the --recursive flag. The command is executed as part of a bash script.
How can I check if the sync process was successful? I've noticed that azcopy doesn't necessarily return a zero exit code even though the sync was successful. Other users have mentioned that checking the exit code with the copy operation of azcopy has worked for them. However, it seems that the story is different with the sync operation.
Currently what I do is delete in my local directory a file that I know will always exist in all Azure containers that I have to sync with azcopy sync. After deleting the file, I run azcopy sync and when finished I check if the file I had deleted was restored... This is clearly not the ideal solution.
I am considering checking the logs from each one of the jobs that azcopy creates, or exploring the --mirror-mode flag or even figuring out if the details provided by --dry-run can help me review if everything went according to plan.
However, all these options seem to be too much for something that should be way much simpler. So, most likely, there is something here that I am missing...

I tried in my environment and got below results:
I tried the same steps in my environment first I copied from storage account to local environment using Azcopy command.
Command:
azcopy copy `"https://venkat123.blob.core.windows.net/container1/<SAS-token>" "C:\Users\xxxx" --recursive`
The above command has copied two files to local environment.
delete in my local directory a file that I know will always exist in all Azure containers that I have to sync with azcopy sync. After deleting the file, I run azcopy sync and when finished I check if the file I had deleted was restored.
I tried the same condition in my environment. I deleted the file is local environment and now I need to sync the file to storage account I used the below commands from local to azure portal.
azcopy sync "C:\Users\xxxxx" "https://venkat123.blob.core.windows.net/container1<SAS-Token>" --recursive --delete-destination=true --mirror-mode
Console:
The above command synced with azure blob container from local environment and it get deleted in azure portal and logs can be seen with above command as below.
azcopy sync "C:\Users\v-vsettu\xxxx" "https://venkat123.blob.core.windows.net/container1<SAS Token>" --recursive --delete-destination=true --mirror-mode
