This is a collection of short shell scripts I have added to my PATH variable to run from anywhere.

To add these to your PATH, clone the repo and add the following to your bashrc or zshrc, replacing <python-scripts> with the location of the cloned repository. Furthermore, see my dotfiles repo for my complete Mac and Linux system configurations.

# Add additional directories to the path.
pathadd() {
  [ -d "$1" ] && [[ ":$PATH:" != *":$1:"* ]] && PATH="${PATH:+"$PATH:"}$1"
}

pathadd <python-scripts>/python2.7
pathadd <python-scripts>/python3
