Simple-SDL

Usage

1. Save the script as SDL.sh.
2. Make it executable:

   chmod +x SDL.sh

3. Run:

   ./SDL.sh /path/to/directory

   If no argument is given, the script will use the current directory (.).

Key parts explained

• stat -c " Access: %x" "$1" & stat -c " Modify: %y" "$1" — print human-readable access and modification times.
• stat -c %X & stat -c %Y — retrieve epoch seconds for atime/mtime to store them.
• ls -la "$dir" — list directory contents with details.
• touch -a -d "@$original_atime" "$dir" & touch -m -d "@$original_mtime" "$dir" — restore the directory's access and modification times.

Technical limitations

• Restoring a directory's timestamps does not remove all traces of activity. Kernel logs, auditd, filesystem journals, or other metadata may still record access.
• The script does not modify timestamps of files inside the directory; only the directory's own timestamps are restored.
• On certain filesystems (e.g., network mounts like NFS/SMB or filesystems with restricted attributes), touch may fail or behave differently.
• Appropriate permissions are required to modify timestamps; if lacking, the restoration will fail.
