loopner (short alias lpn) is a command-line utility to run any command multiple times with delays, error handling, and nice statistics. Perfect for load testing, monitoring, repetitive tasks, and learning.

• 🔁 Repeat a command a specified number of times
• ⏱️ Delay between runs (supports fractional seconds, e.g., 0.5)
• 🚦 Choose error behavior: stop or continue (-k)
• 🤫 Quiet mode (-q) – only the command's own output
• 🗣️ Verbose mode (-v) – show per-run timing and status
• 📊 Final summary: successful/failed runs, total time
• 🧩 Supports any command and arguments (including passing options via --)
• 🩺 Checks command existence before first run
• 🛑 Graceful handling of Ctrl+C and SIGTERM
• 🔗 Two names in the system: loopner and short lpn

loopner [OPTIONS] [--] [args...]

(you can use lpn instead of loopner)

# Run ls -la 5 times
loopner -n 5 ls -la

# Using short name lpn, 3 pings with 1 second delay
lpn -n 3 -d 1 -- ping -c 1 google.com

# Continue even on errors (2 runs, will exit with code 2)
lpn -k -n 2 false

# Quiet mode – only command output
loopner -q -n 100 -- curl -s https://api.ipify.org

# Verbose mode with execution time
loopner -v -n 4 -- sleep 0.5

• bash 4.0 or higher
