doubledown(1) -- sync local changes to a remote directory


doubledown [-i identity] local [user@]server:remote


doubledown brings local and remote on server into sync and then executes doubledown-fsevents(1) to watch local for changes.

An ssh-agent(1) is started if one cannot be found. Because doubledown will connect to server many times over its life, you must use an SSH key pair to authenticate. If you have not created an SSH key pair, do so with the following commands:

ssh-keygen -t rsa -b 2048 -f $HOME/.ssh/id_rsa
ssh <server> "echo $(cat $HOME/.ssh/ >>.ssh/authorized_keys"

When doubledown is run, rsync(1) is used to first download all files in remote on server that do not exist in local, thus no local changes will be clobbered. It then uploads any local changes. Finally, it executes doubledown-fsevents(1).


  • -i identity: Use a non-standard identity (private key). Analogous to the -i option to ssh(1).
  • -h, --help: Show a help message.

doubledown was written to make it easier for DevStructure users to use Textmate and other IDEs but it's far from the only way to skin the cat.

doubledown-fsevents(1) watches a directory and relays changes. It is called by doubledown.
