julia-multi.sh

#!/bin/sh

$SHELL -c '
    echo -e "\e[92mExporting pkg path as:\e[0m"
    export JULIA_PKGDIR="/Users/sean/.julia/v0.4/"
    echo $JULIA_PKGDIR

    echo -e "\e[92mRunning on Julia release\e[0m"
   '"julia $@"'

    echo -e "\e[92mRunning on Julia master\e[0m"
  '"julia-dev $@"

julia-pkgdev.sh

#!/bin/sh

$SHELL -c '
    echo -e "\e[92mExporting pkg path as:\e[0m"
    export JULIA_PKGDIR="/Users/sean/.julia/v0.4/"
    echo "$JULIA_PKGDIR"

    echo -e "\e[92mRunning on Julia release\e[0m"
  '"julia $@"

On my machine, julia is the release branch and julia-dev is the master branch. It's only wrapped in strings because I was curious how to get both bash and zsh to handle it correctly.
