pipe-pane

The easiest way to get logging activated is by following command

tmux  pipe-pane -o 'cat >>~/tmux_output.#S:#I-#P'

This would log the output of the current pane to the file mentioned.
While you can use following substitutions to define your filename:

  • #H Hostname of local host
  • #h Hostname of local host without the domain name
  • #F Current window flag
  • #I Current window index
  • #P Current pane index
  • #S Session name
  • #T Current window title
  • #W Current window name
  • ## A literal `#’

The substitution i choose assure unique-ness on any given point in time, so  you will not overwrite your output. It does not assure uniqueness over the time, so maybe you will have output of the todays session added to a complete different session, which had the same ideas before.

hooks

Maybe there is an option to add the “pipe-pane” command as hook when a new pane gets created. Unfortunately i was not able to find a full list of hooks and unfortunately hooks do not exist with Version 1.8.

The configuration in ~/.tmux.conf would maybe be similar to:

set-hook -g -n 'after-new-pane' 'run "pipe-pane -o 'cat >>~/output.#S:#I-#P'"'

… not working. There are no hooks with my version of tmux.

How to increase scrollback buffer size in tmux?

Tmux has pipe-pane, and it has -I and -O to go both directions.

It does require some gyrations to get around the fact that it logs everything (the command itself, terminal control, etc), and not just what's output by the command. Here's a quick and dirty example:

a) Start a tmux session to a remote host

b) On the local host, run this (assuming session 0):

$ tmux pipe-pane -o -t0 "tail -n +2 | col -b | base64 -d > ~/output"

$ tmux send-keys -t0 "base64 /some/file && read" Enter

$ tmux pipe-pane -t0

$ tmux send-keys -t0 Enter

You should now have ~/output on the local host, which is identical to /some/file on the remote.
