Hey! I'm David, cofounder of zkSecurity and the author of the Real-World Cryptography book. I was previously a crypto architect at O(1) Labs (working on the Mina cryptocurrency), before that I was the security lead for Diem (formerly Libra) at Novi (Facebook), and a security consultant for the Cryptography Services of NCC Group. This is my blog about cryptography and security and other related topics that I find interesting.

Unix command of the day: Tee posted April 2015

The tee command allow you to write to a file and still display the result in output.

For exemple

ls

display the content of the current folder in stdout (the terminal)

ls > file.txt

saves that in a file file.txt

ls | tee file.txt

saves that in a file file.txt and displays in stdout at the same time
