如何在Mac上仅删除以"SAMSUNG"开头的网络服务？

I feel your pain—deleting over a thousand SAMSUNG modem services manually is totally a waste of time. Here's a simple, efficient way to automate the process:

One-Liner Command #

Run this directly in your Terminal (you’ll need to enter your admin password when prompted):

networksetup -listallnetworkservices | grep "^SAMSUNG" | while read service; do sudo networksetup -removenetworkservice "$service"; done

Let’s Break It Down #

Each part of the command works together to target only the services you want to delete:

• networksetup -listallnetworkservices: Pulls up the full list of your network services, just like you did manually.
• grep "^SAMSUNG": Filters the list to keep only services that start with "SAMSUNG" (the ^ ensures we don’t accidentally match any services that mention SAMSUNG later in the name).
• while read service; do ... done: Loops through every filtered service name one by one.
• sudo networksetup -removenetworkservice "$service": Runs the delete command with admin privileges for each SAMSUNG service.

Important Pre-Checks & Tips #

• Preview First: Before deleting anything, run this command to confirm you’re only targeting the right services:

  networksetup -listallnetworkservices | grep "^SAMSUNG"
  

• Admin Rights: The sudo is mandatory here—modifying network services requires administrator access.
• Safe for Critical Services: Since we’re only filtering for services starting with "SAMSUNG", your Wi-Fi, Thunderbolt Bridge, and other essential connections won’t be touched.

Alternative: Verbose Script (Easier to Follow) #

If you prefer something more readable (great if you’re new to shell commands), save this as delete_samsung_services.sh:

#!/bin/bash

# Fetch all network services starting with SAMSUNG
samsung_services=$(networksetup -listallnetworkservices | grep "^SAMSUNG")

echo "Found the following SAMSUNG services to delete:"
echo "$samsung_services"
echo "---------------------------------------------"

# Delete each service one by one
for service in $samsung_services; do
    echo "Deleting: $service"
    sudo networksetup -removenetworkservice "$service"
done

echo "---------------------------------------------"
echo "All SAMSUNG network services have been deleted!"

Then run it in Terminal with:

sudo chmod +x delete_samsung_services.sh && sudo ./delete_samsung_services.sh

Either method will wipe out all those unwanted SAMSUNG modems in seconds instead of hours.
