Because I'm having a conversation on mastodon about enabling "strict mode" with -euo, here's the code:

#!/bin/bash

#
# delete application
#

studio_path="$DSTROOT/Applications/Studio 2.0"

home=$HOME
echo "applications path="$studio_path
echo "home path="$home

if [ -d "$studio_path" ]
then
  # delete all from studio path except "ldraw"
  sudo rm -rf "${studio_path}/" -mindepth 1 -maxdepth 1 ! -name "ldraw" -exec rm -rf {} +
  
  # delete all from studio/ldraw path except "Custom Parts"
  sudo find "${studio_path}/ldraw" -mindepth 1 -maxdepth 1 ! -name "Custom Parts" -exec rm -rf {} +
fi

#
# delete cached files
#

cachedLibPath="$home/.local/share/Stud.io/cachedLibraryPath.txt"
cachedMetaInfoPath="$home/.local/share/Stud.io/BLBrickMetaInfo"
cachedNewPartsPath="$home/.local/share/Stud.io/NewParts"
unityPref="$home/Library/Preferences/com.BrickLink.Studio.plist"
array=("$cachedLibPath" "$unityPref" "$cachedMetaInfoPath" "$cachedNewPartsPath")
for path in ${array[@]}
do
  if [ -f $path ] || [ -d $path ]
  then
    sudo rm -rf $path
  fi
done

exit 0
