File foo.txt exists on the remote machine at: /home/user/foo.txt
It doesn't exist on the local machine.
I want to delete foo.txt using rsync.
I do not know (and assume for the purposes of this question that I cannot find out) what other files are in /home/user on either the local or remote machines, so I can't just sync the whole directory.
What rsync command can I use to delete foo.txt on the remote machine?
Try this:
rsync -rv --delete --include=foo.txt '--exclude=*' /home/user/ user@remote:/home/user/
(highly recommend running with --dry-run
first to test it) Although it seems like it would be easier to use ssh...
ssh user@remote "rm /home/user/foo.txt"
