Hi Kashif

Recently my job required me to learn Linux quickly as I changed my department at work. This course was a pleasant surprise as it covered absolute basics, regular & expert partitioning, and advanced concepts – with hands on live examples. Cannot be more happy with purchase. Thank you Udemy.
