Change Mac Terminal Font Size using Command

You can always go to the Terminal Settings and change the font size of the text of the console, but if you wish to achieve the same using a command on your shell, you can make use of the AppleScript - osascript command.

All you need to do is run the osascript command and tell to change the Terminal application font size to the size that you want - increase or decrease based on the number you provide,

Examples:

osascript -e 'tell application "Terminal" to set font size of window 1 to 14'

osascript -e 'tell application "Terminal" to set font size of window 1 to 24'
