Previously this line was working and was launching the urxvt with a tmux in it:
urxvt -e tmux
… but after my latest install of 18.04.1 Ubuntu it's not launching any more. urxvt version is v9.22.
I've got it successfully started with those command lines:
urxvt -e bash
urxvt -e sh
but no luck with tmux.
How can I start a urxvt terminal with tmux?
