Computer science and engineering's course consist of unix shell script programs in their syllabus. These programs have complexity from simple program to very tough, some of these includes operating system concepts like scheduling, monitors and resource sharing concepts. So to make this thing simple I found some program codes on internet which I want to share with you. 

You can download source code of these program directly from the pages or you can even get the output of these programs here. Please do not forget to put a comment, of you like the content. Some of these Unix shell script programs are very simple ones in terms of other programming language, but shell script is very hard to write. If you make a simple character mistake it would make your Day hard and you need many hours to just figure out what went wrong. You can run these programs by simply copy the code in blank.sh file and then running that file on terminal.

So here is the Complete list.

Copy multiple files to a directory Unix

Count lines and Words Unix

Unix Add and multiply two numbers

Shell script to reverse rows and columns

Factorial of a given number in Unix
