My tmux started to behave in a strange way, briefly.
Today I noticed that my tmux session does not start with a bash shell but instead it starts with ?(no idea). What I can see is just a dollar $.
Then if I try to call bash with
bash it returns
sessions should be nested with care, unset $TMUX to force.
I wanted to add a
default-shell for tmux in the
~/.tmux.conf file, but it doesn't exist and if I create it tmux seems not seeing it.
