Local tmux

  • Run this file to install tmux locally into $HOME/local/bin/tmux
  • I had to run this twice, once on Huckleberry (Power8) and once on NewRiver or Cascades. I just renamed them and created aliases (see ~/.bashrc above)
#!/bin/bash

# Script for installing tmux on systems where you don't have root access.
# tmux will be installed in $HOME/local/bin.
# It's assumed that wget and a C/C++ compiler are installed.
