Bash Jobs

I need a compact, Linux-friendly suite of command-line utilities written in C or C++ that lets me run deep diagnostics on the following components: • RAM Memory • CPU • HDD & SSD (including low-level write/partition and speed tests) • RF-UNIT support where applicable The tools must be completely CLI-driven so they can slot into existing bash automation. For each utility I also need concise professional usage notes—syntax examples, expected output, and any kernel-module or package prerequisites—so a technician can get productive within minutes. Additional scope items: – Benchmark and stress-test options to reveal peak throughput and thermal throttling on RAM and CPU. – Sequential and random read/write tests on block devices, with sm...

I need two simple yet reliable prototype nodes that can sit outdoors, wake up at a configurable interval, pull a register line from a Modbus-compatible soil probe, and push that reading through a Meshtastic link. No commercial polish required—the goal is to prove the data path end-to-end. Scope of work • Recommend and source—or at least specify—a compact board, radio module, and battery pack (AA-powered) suited for outdoor use. I currently have no hardware on hand, so component guidance is essential. • Write Python-based firmware (preferred language) that: – Powers the Modbus interface, retrieves the probe value, and sleeps between cycles to conserve the batteries. – Publishes the reading over Meshtastic in a lightweight JSON or CSV payl...
