With tmux on OSX, how can I make command+k clear more gracefully?

Solution 1:

Configure iTerm2 to send clear command

Preferences -> Keys -> + (add new global shortcut)

• Keyboard shortcut: ⌘+k
• Action: Send text
• value:

clear\n

Alternatively configure iTerm2 to effectively map ⌘+k to ctrl+l

• Keyboard shortcut: ⌘+k
• Action: Send Hex Code
• value:

0x0c

This way you won't see the text flash and the clear command won't pollute your history.

Solution 2:

You can use prefix+r, after the ⌘+K, to redraw the tmux window.

If you can break the habit, a normal ctrl+l works normally per pane.

Solution 3:

bind -n C-k send-keys -R \; send-keys C-l \; clear-history

Got this from here

Props to him. This works for me just like Cmd+k works on the terminal emulator, and works for me on macOS 10.12.5 with iTerm2.

Solution 4:

You can add the following lines in your .tmux.conf:

# clear the current pane
bind -n C-k send-keys C-l \; clear-history

Then reload your tmux config. Now you can use your bind key +k (e.g.: Ctrl+b,k) to clear the current pane.

I don't know the syntax for OSX but I guess you can easily adapt the line.
