Copy file from tmux pane (or window) dir to another pane (or window) dir

Question

Example:

2 panes.

Pane 1 current dir: /a/b/c/d

Pane 2 current dir: /a/f/g

I want to copy file.csv in current dir of pane 1 to current dir of pane 2.

What I do:

In pane 1:

cp file.csv ../../../f/g

It's slow and annoying to find the right relative path from the dir in pane 1 and I feel I could just "drag and drop" the file from one pane to the other.

Is there a way to do something analogous to a drag an drop?

Example of a "good" solution:

cp file.csv $pane2dir

Thanks

Answer 1

I have the following in my tmux.conf

# get directory from other pane using xsel
bind J run-shell -b -t bottom "echo -n #{pane_current_path} | xsel -i"
bind K run-shell -b -t top "echo -n #{pane_current_path} | xsel -i"
bind H run-shell -b -t left "echo -n #{pane_current_path} | xsel -i"
bind L run-shell -b -t right "echo -n #{pane_current_path} | xsel -i"

Often the pane that I want to copy to is to the left or right of my current pane. If it is to the right I would do <prefix> shift-l to put the current directory of the right pane in the clipboard.

To sort of satisfy your solution requirement one could modify this to create a command such as:

cp file.csv $(tmux run-shell -b -t right "echo -n #{pane_current_path} |xsel -i" && (sleep 0.01; xsel -o))

It would make sense to put that stuff in a shell script for convenience.

After giving my answer I played around a little bit and came up with the following

bind L if-shell -b -t right "tmux set-buffer -b panedir #{pane_current_path}" "paste-buffer -db panedir"

which puts the current directory of the "right" pane directly on the command line.
