Pipe directly to a Tmux pane

Question

I've been looking at the available Tmux commands and I can see, out of the box, that I can pipe output from a pane elsewhere or write to the terminal assigned to the session.

I would like to have background processes A, B and C all piping their output to a particular pane in a particular session. How could this be arranged?

Solution

This approach will work if processes were in panes ie. you see there output inside panes not in background

First you have to know the particular pane pts , use this command :

ps ax | grep $$ | awk '{ print $2 }'

The output will be like pts/5

Then we redirect the output of desired precesses pane to this pts 5

tmux pipe-pane -o -t 0.2 'cat > /dev/pts/5'; \
tmux pipe-pane -o -t 0.3 'cat > /dev/pts/5'; \
tmux pipe-pane -o -t 0.4 'cat > /dev/pts/5'; 

-o for open new pipe , -t for target-pane
