The above script goes line by line through your file and removes any duplicative line. Learning this easy and powerful programming method can help you save time, learn the command-line better, and banish tedious file management tasks. You can create a functions file. The command used to search for files is called find.The basic syntax of the find command is as follows: find [filename]. The shell allows some common string operations which can be very useful for script writing. But in Shell script Array is a variable which contains multiple values may be of same type or different type since by default in shell script everything is treated as a string.
