Terminal Tricks to Measure Wifi Strength and What Apps are Using the Internet

For those of you who have never used the terminal program, there are many great things that you can do with the terminal. Here are some new tricks that you can try. My first trick lets you measure the strength of your wifi. To find out the strength of your wifi, just type this into the terminal “/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I” . You will see a number of texts on the screen. Look for “agrCtlRSSI” which will show you the signal strength for your wifi. If you want to figure out what applications you have running that are using the internet, just type in “lsof -P -i -n | cut -f 1 -d ” ” | uniq” and a list of the apps using the internet will appear. If you don’t want to type the script, just copy and paste it in – simple as that! Also, if you want to turn your computer into your talking mouth piece, just type “say (then your text of what you want it to say)” and press enter and it will say what you wrote! Have fun!
