Hi,

Anyone know if its possible to know within tmux if there is any text currently present on the command-line ?

(ie something other than spaces after the shell prompt)  In eiither root or copy-mode.

thx for everything tmux,

You could probably script it with capture-pane and grep and maybe the cursor_y format.

Hi,

Thanks.  I managed this to determine if something was typed -

has_text=$(tmux capture-pane -p | tac | sed '/^$/d' | head -n 1 | awk '{print NF-1}')

(probably don't need the sed to remove esc seq)

take care,
