Getting file size from OSX terminal is a pain. Actually it's a pain in all BSD variants. We normally use `ls -sh` on Linux derivatives. But this command on Mac doesn't return a human readable value.
On that post I wrote about how to enable the warning message forever when using sudo. Now I'm going to write about how the change the warning message and personalize it on your own.
You may have noticed the warning message while using sudo for the first time on Linux. I think it's fancy to keep the waring message not only for the first time but for all the time, and surely I like it.
The issue arises because we may not need the same permission for the files as like the directories. Take a website as example. Generally website files have 644 permission and directories have 755 permission.
