This book is designed to give Sysadmins some entertainment in the form of winding users up (in a non-destructive manner). The book contains tricks ranging from puerile to annoying, all designed for those administering Linux workstations to play on those using Linux workstations!
All are achievable remotely, allowing the Sysadmin to sit back and listen for the sounds of frustration safely out of range of flying staplers. Intended as an exercise in humour, it should provide Sysadmins with some entertainment. Don't expect it to beat a Friday afternoon read of Bootnotes and Odd's n Sod's though!
It's a pretty short book, hence the low price.
Also available on Amazon Kindle.
