In case you need a shell script that can be used to check your internet connection via console, the following script lines could be your friend. The shell script below will perform a wget connection to google with several tries and then returned the value as online or offline string.

#!/bin/bash wget -q --tries=10 --timeout=20 --spider http://google.com if [[ $? -eq 0 ]]; then echo "Online" else echo "Offline" fi |
If you are new to Shell script, you can follow these steps to create a simple shell script/program. I assume you are able to use nano (actually you may use any other text editor you like such as vi).
Create a new shell script file called check-internet.sh
|
1 |
nano check.sh |
Next, paste those code above to the new file
Now save the file and exit. CTRL + X is used if you are using nano to edit the file.
Now make the file executable
|
1 |
chmod +x check.sh |
Finally run the program
|
1 |
sh check.sh |
Output
|
1 2 3 |
[root@gateway ~]# sh check.sh Online [root@gateway ~]# |
