dutchLuck / checkReportedMacOS_ping_short-comings.sh
Created November 27, 2024 09:32
Shell script to check on the short-comings of the MacOS ping utility and its associated man-page that have been reported to Apple through Feedback Assistant
#! /bin/sh
#
# This shell script allows a quick check on whether Apple have done
# anything about the feedback on the short-comings of MacOS ping.
#
# Needs to have a target that responds to ICMP requests (i.e. ping request).
# In my case my local router (192.168.1.1) responds to ICMP requests apart from
# MASK_REQ. Edit "LOCAL_IP_ROUTER" value to suit a different network setup.

LOCAL_IP4_ROUTER=192.168.1.1

Try a quick test of a sequence of bytes specified on the command line to produce a UTF-8 character

// T R Y _ 1 _ U T F 8 _ C H A R

// Display a character from the UTF-8 bytes (or Unicode code point) specified

// N.B. 1. The quickest and easiest access to similar, and probably
// better, functionality as this rust code is to use the following

Read and output up to 1000 (UTF-8) characters from either the head or tail of a file or from stdin if no file is specified:

This "head_tail_file" gist is a contrived example of a command line utility facilitating AI code generation experimentation.

Last active September 30, 2024 12:51
Another (very simple) file byte display/dump command line utility in the Rust language, largely produced by CopilotAI from newbie queries.
//
// F I L E _ B Y T E _ D I S P L A Y
//
// File Byte display
//
// Display the bytes in a small file, or the first 1000 bytes
// of a larger file.
//
// Warning: lacks adequate command line parameter checking
