When working in a shell I would often like the ability to see what public IP I’m on. There is no build in function, which I know of anyway. So after a bit of searching I found this one-line-wonder, and wrote it into a little script.
#!/bin/bash wget -q -O - checkip.dyndns.org |sed -e 's/.*Current IP Address: //' -e 's/<.*$//' echo exit 0
1. Create the script with the command nano whatismyip.sh
2. Paste in the code
3. Press Ctrl+X to exit
4. Press Y to save
5. Enter the command chmod 777 whatismyip.sh to make the script executable
6. Enter ./whatsmyip.sh to run the script
You’ll need nano, wget and sed installed, but that’s default on many distroes.
And yeah that’s not my real IP on the picture.
