How It Works

sleep-tracker manages a simple text-based data log (data.log) where each entry is automatically stamped with the current date. It provides a lightweight way to track health activities, build streaks, and review your history.

Daily Workflow

Log activities: Record what you did — exercise, meals, sleep times, etc.
Check today: Review everything logged today with sleep-tracker today
Track progress: Use streak to see consecutive days and stats for totals
Set goals and reminders: Keep yourself accountable with goal and reminder
Review history: Look at the last 2 weeks with history

Data Storage

All data is stored in $SLEEP_TRACKER_DIR or defaults to ~/.local/share/sleep-tracker/. The directory contains:

data.log — main data file with date-stamped entries
history.log — timestamped log of all commands executed for auditing

The tool automatically creates the data directory on first run. You can override the storage location by setting the SLEEP_TRACKER_DIR environment variable.

Requirements

Shell: Bash 4+
No external dependencies — uses only standard Unix utilities (date, grep, wc, tail, cat)
Works on: Linux, macOS, any POSIX-compatible system

When to Use

Daily health logging — Run sleep-tracker log "8h sleep, felt rested" each morning to build a habit history
Tracking exercise streaks — Log workouts daily and check sleep-tracker streak to stay motivated with consecutive-day tracking
Setting health reminders — Use sleep-tracker reminder "drink water" 14:00 to record reminder notes for key health tasks
Reviewing weekly patterns — Run sleep-tracker history to see the last 14 entries and spot trends in your health data
Exporting data for analysis — Use sleep-tracker export > health-data.txt to get all records into a file for spreadsheet analysis or sharing with a health professional

Health Tips (Built-in)

The tips command provides three core health reminders:

Stay hydrated — drink water throughout the day
Move every hour — take short breaks from sitting
Sleep 7-8 hours — prioritize consistent rest

Configuration

Set the SLEEP_TRACKER_DIR environment variable to change the data directory:

export SLEEP_TRACKER_DIR="$HOME/my-health-data"

Default location: ~/.local/share/sleep-tracker/

Output

All output goes to stdout in plain text. Use shell redirection to save results:

sleep-tracker history > weekly-review.txt
sleep-tracker export | grep "2024-03"
