Summing ps RSS across processes overcounts shared memory: shared read-only pages like the dyld shared cache and frameworks get charged to every process that maps them. With 300+ iOS simulator daemons all sharing those pages, the Simulator group reported ~34 GB when its real cost is ~5 GB. Switch the per-process metric to physical footprint (top's MEM column, what Activity Monitor reports), joined with ps on PID for full command names since top truncates them. Shared pages are now charged once and the grouped sums stay under the system app-memory total. |

My personal collection of command-line utilities. Mostly git workflow stuff, but there's a bunch of other random tools that have accumulated over the years.
What's in here
These are shell scripts, Ruby utilities, and various other command-line tools that live in my PATH. I've been collecting them for ages - some date back to 2006 - and they handle the mundane tasks I got tired of doing manually.
The usual suspects:
- Git workflow shortcuts (because who remembers those flag combinations?)
- Image processing for app icons and retina displays
- JSON manipulation and data analysis tools
- System automation for macOS
- Media conversion utilities
Most follow the Unix philosophy of doing one thing well, though some have grown a bit over time. The ones I still use regularly work reliably, but there are definitely some in here that haven't been touched in years and may or may not still function properly.
