DataView

A data processing toolkit for ingesting, transforming, querying, and managing data entries from the command line. All operations are logged with timestamps and stored locally.

Commands

Data Operations

Each data command works in two modes: run without arguments to view recent entries, or pass input to record a new entry.

Utility Commands

Data Storage

All data is stored locally at ~/.local/share/dataview/:

• Each data command writes to its own log file (e.g., ingest.log, transform.log)
• Entries are stored as timestamp|value pairs (pipe-delimited)
• All actions are tracked in history.log with timestamps
• Export generates files in the data directory (export.json, export.csv, or export.txt)

Requirements

• Bash (with set -euo pipefail)
• Standard Unix utilities: date, wc, du, grep, tail, cat, sed
• No external dependencies or API keys required

When to Use

• To log and track data processing operations (ingest, transform, query, etc.)
• To maintain a searchable history of data viewing and analysis activities
• To export accumulated records in JSON, CSV, or plain text format
• As part of larger automation or data inspection workflows
• When you need a lightweight, local-only data operation tracker

Examples

# Record a new ingest entry
dataview ingest "loaded sales_report.csv 2500 rows"

# View recent transform entries
dataview transform

# Record a query
dataview query "top 10 products by revenue"

# Filter data
dataview filter "region=APAC"

# Search across all logs
dataview search "sales"

# Export everything as CSV
dataview export csv

# Check overall statistics
dataview stats

# View recent activity
dataview recent

# Health check
dataview status
