ssht is a shortcut right into your tmux session on a remote computer.
You can use ssht just like ssh itself. E.g. ssht root@your_remote_computer.com will connect you to your remote computer via ssh, but instead of simply dropping you to a shell, ssht tries to connect you to a running tmux session on the remote computer. If there is no tmux session ssht creates one. No magic, but very handy.
brew tap brejoc/tap && brew install ssht
You can either copy ssht somewhere into your $PATH (e.g. ~/bin) or check out the project on OBS.
Another way is to create your own package with fpm. You can find the Makefile here in the GitHub repository. Depending on your flavour Linux you just have to run make package_deb or make package_rpm and then install the generated package.
Have fun!
