Any idea how I can make a tmux alias for ssh?

I have a nice bash alias for tmux which opens a new window and directly ssh to whatever I specify


<span style="color:#323232;">function s() {
</span><span style="color:#323232;">    tmux neww -n "$1" -- ssh "$1"
</span><span style="color:#323232;">}
</span>

I want to also have something similar directly as an alias in tmux, so I can do C-b :s myhost when I’m already in a ssh to another server, instead of having to change windows, and then run s myhost in bash.

I tried using tmux’s confiug to do various variations of


<span style="color:#323232;">set -s command-alias[100] s='run s'
</span>

Also using directly ssh, or without using run etc. But I can’t figure it out.

In tmux, you usually set configuration options with set -g in tmux.conf. “-g” sets a global option which will apply to all new windows and sessions, otherwise the option applies only for the current window, which is usually not what you want.

Since command-alias is an array, you can use the -a flag to append a new value at the end.

With that said, try this:


<span style="color:#323232;">set -ga command-alias s="new-window ssh foo"
</span>

Keep in mind that run in tmux runs a shell command in the background, so you most likely want to use something like new-window or new-session instead.

This is what I have in my . tmux.conf for SSH you can adapt

bind-key S command-prompt -p “ssh to:”,“port:” “new-window -n %1 ‘ssh %1 -p %2’”

That means when I press C-b, SHIFT S it asks what IP to connect to (type it in when it asks on the status bar of TMUX), press enter, the it asks the port to use.

db0 OP ,

bind-key S command-prompt -p “ssh to:”,“port:” “new-window -n %1 ‘ssh %1 -p %2’”

Brilliant. I removed the port since I usually use my ssh config or I can just type with with : and it’s what I needed. Cheers
