非编程人士求助：Mac环境下将PowerShell作业脚本转为Bash脚本

Hey there! Since you're on a Mac using /bin/bash and need to adapt that PowerShell course script, here's the converted version along with explanations of the key changes:

Converted Bash Script #

echo -e "\nHello Internet World! -- I am here\n"
echo -e "My Name is Norma and today is \r"
date
echo -e "\nAs a net admin testing is an important part of the job\n"
echo -e "You should check for IP information with ifconfig \n"
# Note: On modern macOS, you can also use `ip addr` instead of ifconfig
ifconfig
echo "You should check connectivity with ping"
# Mac's ping runs indefinitely by default; -c 4 sends 4 packets (matches Windows/PowerShell default)
ping -c 4 www.google.com
echo "A..."

Key Conversion Notes #

• Echo behavior: PowerShell uses `n for newlines, but Bash requires the -e flag to interpret escape sequences like \n (newline) or \r (carriage return).
• Date command: PowerShell's Get-Date translates directly to Bash's date command, which outputs the current system date and time by default.
• IP configuration: Windows/PowerShell's ipconfig maps to ifconfig on macOS. For newer macOS versions, you can also use ip addr (a more modern alternative) — I added a comment to note this.
• Ping command: Unlike PowerShell, macOS's ping keeps sending packets non-stop unless you limit it. Adding -c 4 makes it stop after 4 packets, matching the default behavior of Windows/PowerShell's ping.
