Create and manage a case-sensitive disk-image on OSX. This is great when you have a need to work with case-sensitive repos on a mac.

workspace.sh

#!/bin/bash

# where to store the sparse-image
WORKSPACE=~/Documents/workspace.dmg.sparseimage

create() {
    hdiutil create -type SPARSE -fs 'Case-sensitive Journaled HFS+' -size 60g -volname workspace ${WORKSPACE}
}

detach() {
    m=$(hdiutil info | grep "/Volumes/workspace" | cut -f1)
    if [ ! -z "$m" ]; then
        hdiutil detach $m
    fi
}

attach() {
    hdiutil attach ${WORKSPACE}
}

compact() {
    detach
    hdiutil compact ${WORKSPACE} -batteryallowed
    attach
}

case "$1" in
    create) create;;
    attach) attach;;
    detach) detach;;
    compact) compact;;
    *) ;;
esac

Thanx!

Re https://gist.github.com/dixson3/8360571#file-workspace-sh-L7, see https://discussions.apple.com/thread/2001162 on SPARSE vs. SPARSEBUNDLE, the latter may be a better choice.

I was running a setup very similar to this when I upgraded to Mojave I found that mounted disk image's disk performance was so slow as to be unusable. So I made a new image using APFS (Case-sensitive) instead of Mac OS Extended (Case-sensitive, Journaled) and it was much much faster.

For those who end up here, a minimalistic solution here.
