Tesla Commander — Multi-Purpose Utility Tool

A general-purpose CLI utility tool for data entry, management, and retrieval. Provides commands to run tasks, configure settings, check status, initialize the workspace, list/add/remove/search entries, export data, and view system info — all from the terminal.

Command Reference

The script (tesla-commander) supports the following commands via its case dispatch:

Command	Description	Example Output
`run <arg>`	Execute the main function with a given argument	`Running: <arg>`
`config`	Show configuration file path	`Config: $DATA_DIR/config.json`
`status`	Display current operational status	`Status: ready`
`init`	Initialize the data directory and workspace	`Initialized in $DATA_DIR`
`list`	List all entries from the data log	Prints contents of `data.log` or `(empty)`
`add <text>`	Add a new timestamped entry to the data log	`Added: <text>`
`remove <id>`	Remove an entry from the data log	`Removed: <id>`
`search <term>`	Search entries in the data log (case-insensitive)	Matching lines or `Not found: <term>`
`export`	Export all data log contents to stdout	Full contents of `data.log`
`info`	Show version and data directory path	`Version: 2.0.0 \| Data: $DATA_DIR`
`help`	Show full help text with all commands	—
`version`	Print version string	`tesla-commander v2.0.0`

Data Storage

Data directory: $TESLA_COMMANDER_DIR or ~/.local/share/tesla-commander/
Data log: $DATA_DIR/data.log — stores all entries added via the add command, each prefixed with a date stamp
History log: $DATA_DIR/history.log — every command invocation is timestamped and logged for auditing
All directories are auto-created on first run via mkdir -p

Requirements

Bash 4+ (uses set -euo pipefail)
No external dependencies — pure bash, no API keys, no network calls
Works on Linux and macOS
grep (for the search command)

When to Use

Quick data logging — Need to record notes, events, or observations from the command line? Use tesla-commander add "your note here" for instant timestamped logging.
Simple searchable notebook — Accumulated entries can be searched with tesla-commander search <term>, making it a lightweight grep-able journal.
Data export for pipelines — Use tesla-commander export to pipe all logged data into downstream tools (e.g., tesla-commander export | jq or redirect to a file).
System status checks in scripts — tesla-commander status provides a quick health-check output suitable for monitoring scripts or cron jobs.
Workspace initialization — Run tesla-commander init when setting up a new machine or environment to bootstrap the data directory structure.

Examples

Initialize the workspace

tesla-commander init
# Output: Initialized in /home/user/.local/share/tesla-commander

Add entries

tesla-commander add "Server migration completed"
# Output: Added: Server migration completed

tesla-commander add "Backup verified - all checksums match"
# Output: Added: Backup verified - all checksums match

List all entries

tesla-commander list
# Output:
# 2026-03-18 Server migration completed
# 2026-03-18 Backup verified - all checksums match

Search entries

tesla-commander search "migration"
# Output: 2026-03-18 Server migration completed

Check status and info

tesla-commander status
# Output: Status: ready

tesla-commander info
# Output: Version: 2.0.0 | Data: /home/user/.local/share/tesla-commander

Configuration

Set the TESLA_COMMANDER_DIR environment variable to change the data directory:

export TESLA_COMMANDER_DIR="/path/to/custom/dir"

Default: ~/.local/share/tesla-commander/
