I usually open lxterminal with bash shell where I usually type tmux command first.I'd like to have launched tmux command automatically, so I tried to add this command to ~/.bash_profile or to ~/.profile files but none of them launched the tmux automatically.Can this be achieved?
Run tmux always when I open terminal
shell;tmux;terminal emulator
It's really not recommended to do what you wanted , usually I place something similar for ttyX  , edit yor bashrc , add the following lines , which will allow any XTERM based terminal to launch tmux on start.[[ $TERM = xterm ]] && { tmux && exit 0; }You should add a new shortcut or launch terminal with custom shell , which is tmux. ( not sure if lxterm support this )
