SSHH - A SSH session duplicator for tmux
SSHH is a simple helper tool which executes the same SSH command running at a specified window/pane on tmux sessions. You can quickly duplicate your current SSH session into a new pane or window without searching your command history by using the sshh
command.
SSHH is inspired by the cdd command.
Installation
Put the sshh
file to any directory included in the $PATH
environment variable and give the execution permission to the file.
wget "https://raw.githubusercontent.com/yudai/sshh/master/sshh" && chmod a+x sshh
Usage
You can use the sshh
command simply as a CLI tool.
Usage: sshh [window_index],[pane_index] [session_name]
# Run the same SSH command running at pane 0 window 3 in the current session
$ sshh 3
# Run the same SSH command running at pane 2 of window 3 in the current session
$ sshh 3,2
# Run the same SSH command at pane 3 of the current window
$ sshh ,3
# Run the same SSH command at window 1 in the session named `develop`
$ sshh 1 develop
When the process running at the specified window/pane is not the ssh
command, sshh
shows a prompt to ask if you really want to run it.
split-window
Usage with By adding (a little bit tricky) bind-key
settings, you can open a new pane and duplicate your current SSH session into it at once. If you are a Zsh user, add the following lines to your .tmux.conf
. Users of the other shells need to replace the zsh
in the lines with your prefered shell command.
# Assign C-s to split pane horizontally and start a new SSH session
bind-key C-s run-shell "tmux split-window -h \"SSHH_INDEX=$(tmux display -p \",#{pane_index}\") zsh -l\"" \; send-keys ' sshh ${SSHH_INDEX}' ENTER
# Assign C-w to split pane vertically and start a new SSH session
bind-key C-w run-shell "tmux split-window -v \"SSHH_INDEX=$(tmux display -p \",#{pane_index}\") zsh -l\"" \; send-keys ' sshh ${SSHH_INDEX}' ENTER
new-window
Usage with When you want to open a new window, you can write like:
bind-key C-n run-shell "tmux new-window \"SSHH_INDEX=$(tmux display -p \"#{window_index},#{pane_index}\") zsh -l\"" \; send-keys ' sshh ${SSHH_INDEX}' ENTER
Open a new same name window, and close window after ssh exit
bind-key C-n run-shell "tmux new-window \"SSHH_INDEX=$(tmux display -p \"#{window_index},#{pane_index}\") SSHH_NAME=$(tmux display -p \"#{window_name}\") zsh -l\"" \; send-keys 'sshh ${SSHH_INDEX}; [ $? -ne 5 ] && exit' ENTER
