Linux Batch ping script

According to Brother Bird's ping script, I changed it a bit. Used knowledge: Read, Linux read by line, shell output effect adjustment, etc.

Where Linux reads files by line is more important, you can see the link

1 Scripting Features:

Bulk Ping the IP address in the file under the current path, the IP address must be filled in one line

2 Note:

Follow the prompts to run the script to ensure that the script has execute permissions and cannot run on window

Another record: When the Linux function uses the return command, the value of return code cannot exceed 255, and once it is exceeded, it continues to be calculated starting from 0

Linux reads files by line
