CronJob

A comprehensive sysops toolkit for scanning, monitoring, reporting, and maintaining scheduled job operations. CronJob provides 18+ commands for tracking job events, performing health checks, managing backups, benchmarking performance, and exporting operational data in multiple formats.

Commands

Command	Description
INLINECODE0	Record a scan entry — run without args to view recent scan entries
INLINECODE1

Record a monitoring observation — run without args to view recent entries | | cronjob report <input> | Log a report entry — run without args to view recent reports | | cronjob alert <input> | Record an alert — run without args to view recent alerts | | cronjob top <input> | Log a top-level event — run without args to view recent entries | | cronjob usage <input> | Track usage data — run without args to view recent usage entries | | cronjob check <input> | Record a check result — run without args to view recent checks | | cronjob fix <input> | Log a fix action — run without args to view recent fixes | | cronjob cleanup <input> | Record a cleanup operation — run without args to view recent cleanups | | cronjob backup <input> | Log a backup event — run without args to view recent backups | | cronjob restore <input> | Record a restore operation — run without args to view recent restores | | cronjob log <input> | Add a general log entry — run without args to view recent log entries | | cronjob benchmark <input> | Record a benchmark result — run without args to view recent benchmarks | | cronjob compare <input> | Log a comparison — run without args to view recent comparisons | | cronjob stats | Display summary statistics across all log categories | | cronjob export <fmt> | Export all data to a file (formats: json, csv, txt) | | cronjob search <term> | Search across all log files for a keyword | | cronjob recent | Show the 20 most recent activity entries from the history log | | cronjob status | Health check — shows version, data directory, entry count, disk usage | | cronjob help | Display available commands and usage information | | cronjob version | Print current version (v2.0.0) |

Each data command (scan, monitor, report, etc.) works in two modes:

• - With arguments: Records the input with a timestamp into its dedicated log file
• Without arguments: Displays the 20 most recent entries from that category

Data Storage

All data is stored locally in plain-text log files:

• - Location: INLINECODE24
• Format: Each entry is saved as YYYY-MM-DD HH:MM|<value> in per-category .log files
• History: All operations are additionally logged to history.log with timestamps
• Export: The export command can generate JSON, CSV, or TXT files from all log data
• No cloud sync — everything stays on your machine

Requirements

• - Bash 4.0+ (uses set -euo pipefail)
• Standard Unix utilities: date, wc, du, head, tail, grep, basename, INLINECODE37
• No external dependencies, no API keys, no network access required
• Works on Linux and macOS

When to Use

1. 1. Cron job monitoring — Track the execution status of scheduled jobs, log failures, and set up alerts for review
2. Job audit trail — Record scan, check, and report entries to maintain a complete history of job operations
3. Backup & restore logging — Log backup and restore events with timestamps so you always know what happened and when
4. Performance benchmarking — Record benchmark results for scheduled tasks and compare them over time to spot regressions
5. Operational data export — Export all collected logs in JSON, CSV, or TXT format for dashboards, compliance, or further analysis

Examples

CODEBLOCK0

Configuration

Set CRONJOB_DIR to change the data directory. Default: ~/.local/share/cronjob/
