问题:

In shell script,

how to check whether a directory is non-empty on a remote machine?

Regards

回答1:

find PATH_TO_REMOTE_DIRECTORY -maxdepth 0 -not -empty

-maxdepth 0 will make sure you only check the directory, and not all subdirectories recursively.

-not -empty is straightforward.

This will print the path if not empty, and will print nothing if empty.

And, of course, run it via ssh.

回答2:

One possibility is to execute the command mentioned in this answer via ssh:

if [ "$(ssh user@host ls -A /dir/ 2>/dev/null)" == "" ]; then echo "empty"; else echo "not empty"; fi

Note: non-existing directories will also be reported as empty.
