[bash] Efficiently gather dates for logging activity in scripts

dates-bash.md

You can use the date command to include the current date and time in your echo statements. Here are a few common examples:

1. Basic timestamp (date and time):

echo "Converted: $filename → $output at $(date)"

2. Custom format (e.g., YYYY-MM-DD HH:MM:SS):

echo "Converted: $filename → $output at $(date +'%Y-%m-%d %H:%M:%S')"

3. Only the date:

echo "Converted: $filename → $output on $(date +'%Y-%m-%d')"

4. Include both date and time in a single line:

echo "Converted: $filename → $output on $(date +'%Y-%m-%d') at $(date +'%H:%M:%S')"

Example with your script:

echo "Converted: $filename → $output at $(date +'%Y-%m-%d %H:%M:%S')"
