Data Labeler

A data processing and labeling 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.

| Command | Description | |---------|-------------| | data-labeler ingest | Ingest data — record a new ingest entry or view recent ones | | data-labeler transform | Transform data — record a transformation or view recent ones | | data-labeler query | Query data — record a query or view recent ones | | data-labeler filter | Filter data — record a filter operation or view recent ones | | data-labeler aggregate | Aggregate data — record an aggregation or view recent ones | | data-labeler visualize | Visualize data — record a visualization or view recent ones | | data-labeler export | Export data — record an export entry or view recent ones | | data-labeler sample | Sample data — record a sample or view recent ones | | data-labeler schema | Schema management — record a schema entry or view recent ones | | data-labeler validate | Validate data — record a validation or view recent ones | | data-labeler pipeline | Pipeline management — record a pipeline step or view recent ones | | data-labeler profile | Profile data — record a profile or view recent ones |

Utility Commands

| Command | Description | |---------|-------------| | data-labeler stats | Show summary statistics — entry counts per category, total entries, disk usage | | data-labeler export | Export all data to a file (formats: json, csv, txt) | | data-labeler search | Search all log files for a term (case-insensitive) | | data-labeler recent | Show last 20 entries from activity history | | data-labeler status | Health check — version, data directory, entry count, disk usage, last activity | | data-labeler help | Show available commands | | data-labeler version | Show version (v2.0.0) |

Data Storage

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

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 pipeline activities

To export accumulated records in JSON, CSV, or plain text format

As part of larger automation or data-pipeline workflows

When you need a lightweight, local-only data operation tracker

Examples

# Record a new ingest entry
data-labeler ingest "loaded customer_data.csv 5000 rows"
View recent transform entries
data-labeler transform
Search across all logs
data-labeler search "customer"
Export everything as JSON
data-labeler export json
Check overall statistics
data-labeler stats
View recent activity
data-labeler recent
Health check
data-labeler status
