Touch ID Support for sudo in MacOS Terminal for MacBook Pro

Touch ID Support for sudo in MacOS Terminal for MacBook Pro

Well, that was fast. Touch ID is a fingerprint recognition security feature, designed and released by Apple. It is currently available on the iPhone 5s/6/7 and Macbook pro-2016 editions. Many consider it as a huge security win for the MacBook Pro’s. This sounds amazing feature for command line users.

Say hello to sudo-touchid

sudo-touchid is a fork of sudo with Touch ID support on macOS (powered by the LocalAuthentication framework). Once compiled, it will allow you to authenticate sudo commands with Touch ID in the Terminal on supported Macs (such as the late 2016 MacBook Pros). Since Darwin sources for macOS 10.12 are not available yet, this project is based on sudo sources corresponding to OS X 10.11.6 and obtained from opensource.apple.com.

Here is a geeky joke for you:

I was dressed up as an UDP packet for the Halloween. I don’t think anyone got it, but I couldn’t tell.

Find the oldest file in Unix or Linux file system

Find the oldest file in Unix or Linux file system

So I wanted to know the oldest file on my Debian Linux box.

find / -type f -printf '%T+ %pn' | sort | head -n 1
Here is an another example for /etc/
find /etc/ -type f -printf '%T+ %pn' | sort | head -n 10

Find the top 10 oldest file in a directory tree on GNU/Linux

Find the top 10 oldest file in a directory tree on GNU/Linux

So find command finds all files in / and print it with a special format. The %T+ (in -printf) means file’s last modification date and time in separated by +, for example ‘2004-04-28+22:22:05.0’. This is a GNU extension and may not work on other BSD/find or any other version of find. The %p indicts the file name. The sort command sorted input and passed it to head to display the oldest file on my GNU/Linux system. The sort command sorted input and passed it to head to display the oldest file on my GNU/Linux system. Cool, eh?
