This project aims at compiling solutions for Flex Your Brain exercises appearing at the end of each chapter in the book UNIX Concepts and Applications - Fourth Edition, authored by Sumitabha Das.

The book is a recommended reading for many Computer Science, Computer Applications and Information Technology courses across universities in India. It is also quite popular among students who are UNIX and GNU/Linux, newbies.

The questions covered under Flex Your Brain exercises are slightly involved, and the solutions for the same are not made available with the book. This project aims to create a study aid for students by compiling the same.

The exercises are solved and tested on computers running:

• macOS Catalina 10.15.7 (19H2), a POSIX compliant UNIX operating system, which is developed to run on Apple's Mac computers.

• Ubuntu Desktop Linux 20.04.1 LTS (Focal Fossa), a free and open-source Linux distribution based on Debian.

Both the computers are running version 5.0 of GNU Bash as the choice of shell.

All the efforts have been made to ensure correctness and completeness of solutions while keeping the differences between the two platforms in mind. However, it is advisable to refer to the system provided documentation for commands (using man pages, info pages or online command help documentation as available).

The following conventions are used:

• Key terms are shown in Bold

• Command line, expressions and symbols are wrapped in backticks

• File and path names are italicised
