These are how I setup my src folder as case-sensitive on an external drive due to my shitty 128Gb macbook.

src-external-case-sensitive

## Steps used to setup the ~/src 

1. Create a virtual disk on my external hard drive

Install the script https://gist.github.com/scottsb/479bebe8b4b86bf17e2d

mkdir /Volumes/SAMSUNG/disks/

1.1. Review config

➜  src /usr/local/bin/casesafe.sh config
The behavior of the script may be modified by seting the following environment variables.
If not set the script will use sane defaults.

CASE_SAFE_MOUNT_POINT
    Location where case-sensitive volume will be mounted
    Current effective value: //Users/neisantos/src

CASE_SAFE_VOLUME_PATH
    Location where image file should be stored
    Current effective value: /Volumes/SAMSUNG/disks/.casesafe.dmg.sparseimage

CASE_SAFE_VOLUME_NAME
    Name of case-sensitive workspace as visible in macOS Finder app
    Current effective value: src

CASE_SAFE_VOLUME_SIZE
    Maximum size of volume (will auto-grow up to this)
    Current effective value: 100g

/usr/local/bin/casesafe.sh create
/usr/local/bin/casesafe.sh mount

2. Run Strap
