When you SSH into a remote box, you get all the features of Warp without any configuration on your part. The input editor, auto-completions, and history search work the same, regardless of machine.
- Warp specific features like Blocks are currently supported only for bash or zsh.
- If you're using a different shell, you'll want to use
/usr/bin/sshdirectly (see below for more details).
- For zsh, xxd is required to bootstrap warp.
If you're using zsh on the remote host, we create a temp folder to act as the ZDOTDIR during the bootstrapping process and remove it when the shell is set up.
We create a wrapper (around
/usr/bin/ssh) to set up the shell for Warp's feature set. We authenticate normally using
/usr/bin/ssh, and bootstrap the remote shell to work with Warp Blocks and the Input Editor. You can opt out of this functionality by invoking
- Warp takes over the prompt which enables us to build a modern input editor.
- Warp configures histcontrol to ignore commands with leading spaces. We do this so our bootstrapping code does not clutter the history.
You can see the SSH wrapper by using
which warp_ssh_helperin Zsh,
type warp_ssh_helperin Bash.
If you're seeing these errors, you may have some config on your server (usually in
/etc/ssh/sshd_config) preventing Warp's ControlMaster connection from working. In this state, completions that require information from your remote host won't work and your history also won't work.

Write access in
/etc/ssh/typically requires sudo access. After any edits, you'd also need to restart the
