#!/bin/bash # Script to compare actual file stats with override stats from xattrs # # Usage: ./compare_stat_overrides.sh [-L level] <directory> # # Description: # This script displays the actual file stat (uid:gid:mode) alongside the # user.containers.override_stat xattr value if present. This allows easy # comparison between the real file permissions and the virtualized ones. # # Options: # -L level Descend only level directories deep (like tree -L) # -a Show all files including hidden files # -h, --help Show help message # # Examples: # ./compare_stat_overrides.sh . # Compare stats in current directory (all depths) # ./compare_stat_overrides.sh -L 2 /home/user # Compare stats up to 2 levels deep # ./compare_stat_overrides.sh -L 1 -a ~/ # Compare stats 1 level deep, including hidden files # # Notes: # - Requires 'xattr' command to be available on the system # - On macOS, xattr is built-in # - On Linux, you may need to install 'attr' package # Default values MAX_DEPTH="" SHOW_HIDDEN=false DIR="" TOTAL_COUNT=0 # Parse command line arguments while [[ $# -gt 0 ]]; do case $1 in -L) if [[ -z "$2" ]] || !
