v1.0.0

Stable release :)

v0.0.2

Initial release (with just a little fix) 🎉

A humorous POSIX shell script that estimates distance from ping RTT based on the speed of light.

Features

• Four transmission models: --fiber (default), --copper, --theoretical, --dialup
• Force IPv4 with -4
• Limit packet count with -c
• Output mimics standard ping(8) format
• Statistics summary on Ctrl+C (RTT + estimated distance min/avg/max)
• Strictly POSIX: no bashisms, no GNU-isms, no PCRE

Compatibility

• Debian GNU/Linux (Bookworm, Trixie) arm64/amd64
• FreeBSD 13.x / 14.x
• macOS (Darwin) Ventura, Sonoma, Sequoia

Fun facts

• --copper and --fiber give the same result within ~1% - the real troll is in the physics
• --dialup subtracts 120 ms of modem overhead - back then, the world was smaller
• Originally written in 2002 at Club-Internet on 36 lines of Solaris shell
